Hi @vidguy7 ,
Here are links to the topics that discuss your questions:
Thanks Sam. Actually, our solution is a bit more technical than you might imagine. All sonic anemometers face the challenge of dealing with obstructions in the sonic path. Even slight changes in the sonic path distance can throw off the timing of the return sonic signal. To deal with obstructions like rain drops, we have developed an algorithm that inspects all wind data in real-time. Any data that looks suspect (by virtue of algorithmic rules, which will get better and better with more data) g…
We recently had an unusual phenomenon, when a cold front dropped the temperature by 9° C in a matter of about two minutes. This was confirmed by both my Davis and Oregon stations. In both cases, Weather Display showed the drop over about five minutes, with a slight delay due to the thermal inertia of the sensors.
WeatherFlow took over an hour to respond to the change of temperature. I believe this to be due to the thermal inertia of AIR with the mass of the batteries.
The question is whether t…
I have not witnessed or read about anyone having a delay with their pressure reading. But I believe it does adjust itself to your local area so it may have been calibrating itself.
Hi @moeythomas . We agree that having to fudge your elevation to calibrate your sea level pressure is NOT THE RIGHT APPROACH…and to be clear, this is not the approach that WF is taking.
Here is how it actually works: AIR will sense the pressure at it’s location (station pressure). To normalize and compare against other stations in the area, total elevation needs to be taken into consideration…which is then used to calculate sea-level pressure…so that everyone is comparing apples to apples. …
Your SKY / Tempest leaves the factory with a wind sensor calibration in place. To ensure in-situ accuracy, the sonic wind sensors in SKY / Tempest are designed to self-calibrate over time once installed in the field. The initial in-field process requires collecting a certain amount of data at all four cardinal points. This initial process runs through a check to ensure all four sonic sensors are balanced properly.
For those of you with access to a calibrated wind tunnel, or reliable testing equ…

my station # is 6187
Dear Weatherflow enthusiasts.
Often when someone reports a problem/bug related to her/his station, we have to ask to give us her/his station details. Without, the chances someone helps is slim (even staff can’t guess your station’s id)
Maybe we can all edit our profile page and insert the link there, at least we won’t be asking the same question over and over again. Clicking on your avatar and … follow the link.
You can find your link on your online station’s page if it is set public (for pri…
Many questions and answers have been discussed in this forum with no easy way to find a complete FAQ. Because this station is continually evolving and changing, even your own station will be automatically updated and calibrations will change and you wouldnt know it unless you read it here somewhere. I use the search bar a lot to find things out.
cheers Ian
