They use public airport weather data
- dfc 13y agoWho is "they"? I am assuming you mean openweather. Given that the page linked above details the use of personal weather stations you certainly cannot be referring to WeatherUnderground. Where did you find the source of the data for openweather? Addendum: See my comment below. The number of airports and airfields visible from the air does not get you over 45k.
- pellias 13y agoYup, when i zoomed in to see the station information, all of them are airports.
- dfc 13y agoThe numbers do not add up. According to the CIA in 2012 there were 43,794 airports or airfields that are recognizable from the air. This number includes airfields that are "unpaved (grass, earth, sand, or gravel surfaces) and may include closed or abandoned installations." The 2010 figure is 43,982.[2][3] [1] https://www.cia.gov/library/publications/the-world-factbook/fields/2053.html https://www.cia.gov/library/publications/the-world-factbook/...
