WMO Average Temperature

Average daily air temperature is calculated for each WMO station by averaging the daily maximum and minimum air temperatures. The dekadal average air temperature is then estimated by averaging the ten daily air temperatures for each WMO station. Any WMO station that reported eight days or less is eliminated and maps are then generated by Inverse Distance Weighting interpolation method.

Daily ground station data is from the World Meteorological Organization’s (WMO) Global Telecommunication System (GTS), which is a global network of more than 6000 stations. However, many of the 6000 stations do not report to the GTS daily, but approximately 3800 stations report each day.
