[wxqc] Barometric Pressure Errors

[Steve Hatchett]

Which software program are you using to upload to CWOP? If WeatherLink, make
sure you are using the latest version. Also make sure you have the correct
elevation entered into your console.

The VP displays Sea Level Pressure, but CWOP wants altimeter. At your
elevation it's an important difference. To submit the correct Altimeter
value, you need to use software that calculates the altimeter value from the
console's sea level pressure, and then sends that altimeter. The latest
version of WeatherLink will do that, and there are several other programs
that do it as well. But some don't.

Searching the "Net" to try to figure out why my brand new Vantage Pro 2
barometer tracks 3 or 4 mb's plus or minis over a period of a few days. I
ran across your inquire as to the same problem.  Notice your quality checks
are 2 thumbs up now. May I ask what did you finely do to correct this, set
to zero elevation? I am at 5454ft.

My old weather monitor II was just set to zero and I added 5.35 inches
through software for years with great results.

 

I found lots of references but no solutions.

I would greatly like to know what you ended up doing.
