** Note: The 3 high-resolution data sets take a while to load - please be patient.

 

Click on a data source to go to a map from which you can obtain estimates of mean wind speed (m/s) for the period of data overlap (1979-2000) and the trend in the annual mean wind speed (%/yr) for the entire data record. If the trend column is empty the temporal trend is not statistically significant.

 

Note:

All wind speeds pertain to a nominal height of 10 m a.g.l.
