E-OBS climate indices

 

EUPORIAS logo

 

The datafiles below provide 31 climate indices (ETCCDI indices marked with *) for the E-OBS gridded dataset (v11.0) derived using daily minimum temperature (TN), daily maximum temperature (TX) and daily precipitation sum (RR).
They cover the area 25N-75N x 40W-75E with 0.25 deg regular grid.
The data files are in NetCDF format, separated in three sets per index: annual, monthly and seasonal. Seasonal indices are calculated from the monthly indices, where for December-January-February (DJF) the December of the previous year is used: Dec(1951)-Jan(1952)-Feb(1952).
