I remember when Watts first proposed this. He had pictures of weather stations next to AC compressors, trash burn barrels, and one just off the end of the runway subject to regular jet wash. When he started to organize volunteers to go to every site in the county to verify it was in the recorded location and away from buildings and pavement, NOAA took the location list off the web “for privacy purposes”. Nope, you can’t go double check the government’s work, peasants).
