Personal Weather Stations at Weather Underground

Over the past 4+ years, Weather Underground's community of Personal Weather Stations has grown into a large contingent of thousands of stations that continues to grow on a daily basis. These stations have allowed our users to see what the weather is doing not only in their zip codes or neighborhoods, but on their street itself.

We are excited to see the numbers of Personal Weather Stations increasing, especially in recent months, so we have created this environment to help create a tighter sense of community amongst not only our Personal Weather Station owners, but also our members in general.

Due to the varying number of platforms and software packages capable of uploading station data to us, a variety of problems can and do arise during the configuration process. This environment will provide a quick way of getting solutions to these problems in case I cannot get to them right away.

We want the Personal Weather Station project to continue to grow...and this where you come in. Please let your family and friends know of the project and urge them to get in on the fun. Personal Weather Stations are going to be very important in transforming meteorology from a non-exact science into at least a more-exact one.

Lastly, as a trained meteorologist I love watching weather develop and tracking it around the world. If you have any interesting weather related stories that you would like to share, I would like to hear them. Better yet, if you are a Personal Weather Station owner who captured interesting weather (strong frontal passages, wind gusts, dramatic swings in temperature) via your station's data, post it here!

Quoting shauntanner:
I agree, some stations are position in places that are not good for data collection. When these stations are pointed out, I usually write to the owners to offer help in getting the station in the correct place. Please let me know of any station that seems to be reporting bad data.


It doesn't seem to work all that well. Weeding out these stations here was easy though. I have been on since 2002 and have seen 4 other stations come online. I also saw the return of our airport station after it was destroyed by 121mph straight line winds. I will not mention the damage it did to me. However it’s very hard to talk with them thru Wunderground as the msg system works here only. It doesn't send to their primary email address and often go unnoticed because of it. It is rude to gps these people and go talk to them one on one. It took 1 year for 1 station to do ASL baro correction. Other station operator I knew went completely offline simply because we were so close it was useless, and he was moving anyways. Now there is a station online locally that simply produces temp data and nothing else. I am the one being yelled at because I am the 1st pws in my community, and people look at all the data from all stations to make their daily plans. So when they see some bad data guess who they email. I have a website and they make good use of its emails. You need to make the msg's sent thru your system also send emails to the address they sign up with. Essentially I have not found the msg system here helping in weeding out the bad stations. It's not easy. These stations may simply need help, but without a direct way to contact them most never see the msg's they get thru here. I have missed more than 3 dozen over the years that I didn’t notice till months later. So believe me I know what I’m talking about, and i hate hitting that report button as i have never seen anything done to the stations reported here. Sorry Shaun but this one has me wondering. Thanks though Wunderground rocks.

With one of the more popular weather forums having recently been acquired by a commercial weather services firm - who is actively supporting the bill introduced by Senator Santorum (PA) that, according to many, would strip the National Weather Service of much of its duties and responsibilities - I created a new weather-oriented forum as an alternative for those who choose not to make the move with the other one. Weather enthusiasts of all levels are welcome, and there are a number of specific topic areas relating to personal weather stations, hence my posting here. If you'd care to pay us a visit, we're at weatherforum.net.

I've noticed a number of questions about accuracy and positioning of weather instruments. May I suggest that everyone wanting to maximize their data accuracy review the Instrument Siting Guide produced by the Citizen Weather Observer Program (CWOP) that transmits data from Personal Weather Stations into NOAA servers where the data is used in forecast models and for many other purposes. You don't have to participate in CWOP, of course, to benefit from the guide. But most software that will send data to the Weather Underground will also send it to CWOP, and I'd encourage everyone to participate in this program. It's truly a community service. As with Wunderground, your data will also be posted to the internet, and can undergo automated quality checking if you so desire. You can see my data here and one of the automated quality control check of my data here.

In the interest of disclosure, I'll mention that I was one of the technical editors of the CWOP guide mentioned above.

Aero,

I've been involved with electronic instrumentation for a number of years. Most of the electronic instrumentation that I've used is quite reliable, if the transducers are designed and built properly. As far as temperature transducers, the biggest culprit I've seen is moisture destroying resistance devices such as RTDs and thermistors. If the probes are properly sealed such that moisture cannot leak in and saturate the chip, my experience is that they work fine and retain their accuracy.

I find it particulalry odd that a weighing device would be so unreliable. Electronic scale technology has been around for "ages", relatively speaking. Electronic scales are frequently used in industrial applications, and can built to be quite robust.

TO: Tom of Carter Lake

The source that I have that Electronic
temperature sensors and readouts become inaccurate over time is my 41 years working in the field of Meteorology and climatology, I personally installed 140 electronic units and know how inaccurate they can become over just a few years in the field. Even worse are the electronic automatic rain gages that most climatologists and hydrologists refuse to use because of their "splash by" or under reporting of heavy precipitation, because the tipping bucket can't keep up with heavy rainfall.
The Official 8 inch manual rain gage is still the most accurate and the Standard that electronic rain gages are measured to.

I work currently at an airport with the latest weighing type rain gage and it needs constant attention by maintenance personnel. I always check it against the manual gage and often find errors and even gross errors by the automatic electronic weighing telemetered gage.

Somethings can be automated in life, and there are other things that can't be, ie, the visibility sensor used with the ASOS (automatic surface observation system) at major airports
reads good in high visibility conditions with no sector variability, but when the visibility gets low, especially with sector visibility differences the automatic sensor sends out erroneous data frquently.

The Sky condition sensor on ASOS also
does a poor job of reading the layers of clouds and heights of cloud bases.
The height sensor reads not only the base of towering cumulus clouds but also the buldges of the cloud as another layer.. Also the height sensor can't read cloud heights over 12,000 feet.

Worst of all is the cloud layer amount as read by ASOS. Often ASOS reads
a SCT condition as OVC or BKN because it apparently has a difficult time figuring the cloud speed.

The most common failure on ASOS is the
dew point sensor that needs attention often. The Wind sensor freezes up in Freezing Rain or drizzle.

Because the unit is subject to all out
failure at times, a manual observer must read the liquid in glass thermometers every six hours plus at midnight at major airports.

ASOS can't read the amount of new snow every hour, or total snow depth on the ground.

The problem with weather observers is that they want a simple solution because they are too indolent to melt down a can half full of snow, and settle for a less accurate method of heating the can, causing evaporation.

I'm sticking with the Standard... Manual Instruments and the exercise
walking out to the instruments is
healthy.

Hi Greg,

Oops, forget my question about vanprod. I tried at the other perl script polldavis.pl a while back to see if it would work and it did not (but I figured it was the USB thing).

Now that you say vanprod works, I will definitely give it a try. If I can see how he communicates, I might be able to adapt it to my Java program.

Thanks for your input.

Hi Greg,

That's good news. What is vanprod?

I know what you mean about writing to /dev/tty.SLAB_USBtoUART, I can open it and send data with no errors but I don't get a response from the console.

With one exception: if I start up WeatherLink so it initializes the device then I can communicate with the console just fine. As soon as I stop WeatherLink, my software no longer talks to the console either.

So I must not be initializing something properly.

I'm glad to hear that you have it working though; that means there is hope! It is frustrating having to rely on that dang PC'ish Davis software. It hangs requiring a restart every so often.

Thanks!
Kev

Kev,

I'm using a Vantage Pro2 on an iMac (20" G5, OS X Tiger) with the USB no problem. I use vanprod to query the station and upload to Weather Underground (station ID is KINBLOOM9).

The Vantage Pro console appears as an ordinary TTY device via the Silicon Labs USB to serial interface. You just read/write to /dev/tty.SLAB_USBtoUART just like a serial device.

I have read several posts about accuracy. While I totally agree you should make sure that your sensors are accurate to actuals at your location, I do not necessarily agree with checking them against other local readings. Readings change rapidly with elevation and due to other nearby environmental influences. While I check my own equipment against a mercury thermometer and a sling psychrometer I have no interest in comparing or better yet adjusting my readings to the local METAR which is at the airport only a mile away. If I am just going to have my readings match the local METAR, whats the point of having my own weather station.

I think we need to remember with a PWS we are measuring conditions in our own environment. If the electronics are accurate then what they read is what they read. I am reporting weather in my backyard. I know that the wind speed is not accurate to the "outside" world, but it is the wind I am experiencing in my backyard and is also likely what my neighbors are experiencing.

Never understood why most of the weather is recorded at the airport. Who lives at the airport anyway!!

Just my two cents.

It is understandable that a humidity sensor can be contaminated by dust, fingerprints, etc. If you live near the ocean and get salt dust and spray, it can cause massive errors on the sensor by making it more conductive and read a higher humidity. Most of these sensors can be cleaned by soaking in distilled water to dissolve off conductive salts. You may also be able to use some industrial solvents like TriChlorEthane of top quality rubbing alcohol if contaminated with other substances.

However a temperature sensor that goes bad or out of calibration after time is a bad design to begin with. If a small junction with two bare wires swinging in the breeze is considered accurate, it is only accurate in a sheltered existence, which means a lab. The outdoors temperature sensor and all surrounding devices need to be sealed against moisture and harsh conditions to prevent corrosion and contact with dust, salt, etc.

A good electronic sensor should be able to match the best liquid thermometers out there if properly engineered, and then avoid the human error factor, or simply the human lazy factor (me). Many electronic sensors are used in industrial production applications, and if they were to go this far off accuracy in such a short time, there would be some big problems with the parts manufacturers reputations.

Personally I have seen the inside of some of the more popular weather stations, and I am not impressed. Wires exposed when they should be coated, junctions up in the breeze with exposed wires that are prone to RF interference and weather damage, and so on. I understand that the costs have to be kept down, but some things just dont cost that much more.

However I was appalled at the inaccuracies of one weather system I brought home thinking I was going to use last year. I wont name names but you can probably guess. I managed to land 3 remote temperature sensors with it, so to check them out; I lined them all up together inside on a small table. They all read at least 5 degrees apart after sitting there for 12 hours! Something like 71, 77, 74, but I dont remember for sure. I just couldnt take that and took the whole pile of crap back. Then I saved money for the Davis system which I bought this year, and was impressed that after leaving the console and remote sensors together overnight, the temp and humidity of both matched exactly.

well i have had a humidity - temperature digital sensor that was ruined by rain and dust storms and it became inaccurate in only 2 years. temperature was above the real reading by 2 degrees C and humidity was below the real reading by ~10%. I agree that the mercury thermometers are more accurate reliable and durable.

Aero, your claims of digital thermometer inaccuarcy are quite interesting. Can you quote any sources for your claims?

Obviously, the automated digital weather station was created to remove the human element from weather measuring. This by far is the single greatest problem in collecting data - i.e. human reads wrong information; human has a life and wants to live it, etc.

Whether the network is 1 or 228, regular calibration checks should eliminate any possible equipment failure or drifting. And meanwhile, such equipment - properly installed - will measure weather data every second of every hour of every day, day in and day out with near perfect accuracy... something a human is just not designed to do.

For the personal weather station owner, the Citizen Weather Observer Program offers a wealth of helpful suggestions (like regularly checking readings with another sensor) and data quality checks (automatically comparing weather stations' against one another).

I believe in accuracy and use the old
fashioned Official standard Liquid in
Glass Maximum Thermometers, and a
metal 8 inch rain gage along with
snow board. Having worked in the field
of Climatology Managing a Network of
about 228 sites I know how electronic
thermometers can lose their accuracy
over time, usually about 2-4 years and
they are often worthless, sometimes
reading 3 to 4 degrees F. one way or the other or worse. Sometimes the Observer doesn't know that his thermometer is reading 1 or 2 degrees off and the data gets published as an official record of the NWS, effecting
Global warming studies.

With the Official Standard Liquid in glass thermometers it is obvious when they are not accurate. The yellow alcohol in the Minimum thermometer will sometimes seperate when the Instrument shelter vibrates in high winds, and it is very easy to reunite the fluid, but tapping on the metal backing for the
thermometer, holding the bulb in down.

Maximum mercury in glass thermometers
rarely become inaccurate unless the glass is cracked.

Is there a way I could send my accurate data to The Weather underground ?

KevDev,

Since I only have the Vantage Pro I only tested with it. The communication specs for the Vantage Pro and Vantage Pro 2 are the same. I've also only used the Serial version of the WeatherLink cable which also works on the Vantage Pro 2 so my software shouldn't have an issue with talking with either the original or 2.

I'm going to order the USB version of the WeatherLink cable to see if I can test with that.

As to the communications, using the serial WeatherLink, I just talk to the console using Davis' published specs.

I have enjoyed observing local obs for a few years. The only thing that is frustrating & that will prevent this from becoming more of an exact science is the inaccuracies of some stations. You can definatley tell when the thermometer sensor is placed directly in sunlight!

AfterTen and Other Mac Users,

The VantagePro 2 for OS-X uses USB as opposed to a USB-to-Serial adapter. USB is converted to RS-232 inside the VantagePro 2 console itself using a USB to UART bridge chip manufactured by Silicon Labs. The problem I am having relates to communicating with their SLAB-USBtoUART driver. Davis has been of little help, so I left an email with Silicon Labs.

If they can give me an interface protocol to their driver, than I should be able to make a standalone Mac application that polls the VantagePro 2 w/USB and uploads to wunderground.

I am uploading now, but it is a two stage process where I use Davis's WeatherLink software to poll the VantagePro2 and then my software to upload to wunderground. This is fragile at the moment.

AfterTen, How do you poll the VantagePro console? Pehaps I can learn something from what you have done.

Shaun - Please see my e-mail I sent you. There seems to an issue with many of the Personal Weather Sites posting to Weather Underground. The graphs tell the story...many peaks and dives that are completely unexplained. It seems when information is sent to your server, a time other then when it is sent is put on the delimited comma file. An incident that I caught today posted my 12:00pm reading as 9:00am which gave two 9:00am reading causing my banner to read "No Data" and my graphs to completely wrong. I've noticed this same thing occuring on many of the personal weather sites.

I'll be releasing the first "Preview/Beta" of a Macintosh program that collects data from personal weather stations this weekend. (It will work on Windows too but Mac is my target audience since there are plently of PC programs out there)
My Forum Announcements

It works with Davis Vantage Pro (should work with Pro II but I haven't tested that) O.S. WMR968, Davis Wizard and LaCrosse 23XX series. I'll support more stations in the future.

Program will allow you to post data to a personal web site. See...
Here as an example.

It also uploads to WeatherUnderground.

Anybody else had any problems with delivery of replacement parts from Oregon Scientific? My THGR968 module broke and I've tried since November to get another one. I've even written OS on several occasions and got the usual "sorry for the delay" reply. I purchased one of their new big wireless stations and my THGR968 came loose from it's mount, hung upside down, filled with rainwater and froze last November. I'm about ready to throw this thing in the trash and learn not to purchase anymore OS products.

Will anything else work for this? I have no outside temp or humidity without it.

RE: intentional GPS inaccuracy

The SA (Selective Availability) has not been used for several years. Consumer grade GPS receivers get just as acurate information as anything else for the type of receiver used. Now it is true that there are a couple of kinds of signals available from the satellites and most consumer grade GPS only receive the simplest type. Still, I can walk into any good surveyors supply store and buy a GPS that will give me sub-centimeter accuracy (if I have the big-bux required).

Greater elevation inaccuracy is due to the geometry of the satellites rather than any intentional inaccuracy; it is also the case that 50' of altitude error is a lot more annoying than 50' of horizontal error. You can walk over to something 50' away, but if it is 50' over your head, that is something else again.

I am in the process of writing software that will allow OS-X Macs to upload data to wunderground from a Davis Vantage Pro 2.

It is a little 'clunky' now in that it is a two-step process of using Davis' WeatherLink software to actually get the data from the Vantage Pro 2 console and then my program to upload that data to wunderground.

I'm trying to learn how to poll the Vantage Pro2 myself so I can make a single program to do all the work.

If I get that done, I will gladly make the program freely available so more Mac users can get their weather stations online.

In the mean time, you can play around with the perl scripts that were written for Linux at http://www.wunderground.com/weatherstation/index.asp
I know of one person who is using one of them with a Mac.

CWOP has a pretty good quality control system in place. If you upload your data to them, you can get your own QC page, and you can check your data quality every day against nearby stations, amatuer and professional. Foe example, here is what mine looks like. (Okay so nobody is perfect. I'm working on it!)

CWOP has also developed an excellent downloadable document that details setting up your station. There is much, much more if you are interested.

"Is you script available for use? " Not sure what you are refering to, I guess so. I never played around with the scripts.

I agree, some stations are position in places that are not good for data collection. When these stations are pointed out, I usually write to the owners to offer help in getting the station in the correct place. Please let me know of any station that seems to be reporting bad data.

Kevdev: I also have a G5 running weatherlink. Is you script available for use?

I've been thinking about putting up a weather station. Anyone have theres running off of a Mac?

The only comment I have is this. Just because we all have these weather stations, doesn't mean that they are really reliable. Some of the people in my area keep their heat monitors in direct sunlight thus giving a wrong humidity and heat reading. And depending how high and where you put your wind gauge, you will get vastly different readings than your neighbor. As is the case in my instance. I don't have my wind gauge mounted on top of the house so it doesn't get the right wind direction or speed at all.

Base line here. We all need to make sure our devices are mounted and calibrated to make sure that people that do go to our sites can see them and feel good that they are getting quality information.

Davis Vantage Pro Weather Stations on Sale 50% Off

Davis is clearing out their Vantage Pro's because they have recently released a new station called Vantage Pro2.

I personally own this type of weather station, and it gives the most detailed and accurate measurements.

I though I'd pass this sale information along for those who either are considering purchasing a weather station or might upgrade their current weather station.
