TDL U.S. and Canada Surface Hourly Observations
Listed in National Center for Atmospheric Research
Hourly airways data over US, Canada for about 2000 stations.
Description
There are also some observations for Mexico and most Central American countries. The data is taken directly from all the METAR reports.
METAR data includes ASOS, AWOS, and non-automated reports. Some reports might not report wind. However, during the quality control, if there is a wind direction reported greater than 360, it is taken as an error and changed to a missing value.
