You don't need Phillip to fix this problem.
All you have to do is send an email to CWOP-support at noaa.gov and provide your CWOP ID and tell them that you would like to correct your station elevation. And you provide them with the correct information in meters which should be around 140 meters. Do not send information in feet.
You should also send a second email with the same information to MesoWest.
Gladstonefamily.net information will get automatically updated when you do as I've stated.
What source does CWOP/NOAA use for elevation? For example, I just registered my station at our cabin that I just installed. The ones that match my home elevation I used for the cabin. CWOP page says it is off by 57 feet (4,167 vs their 4220 estimation). I did ask Leigh about this but never received a response about the elevation, just to correct the lat, long slightly in my software, which it was already correct, just the point on the CWOP map was off.
