Version 2.0

A global gridded dataset of the SPEI drought index is computed, at time scales between 1 and 48 months, at a spatial resolution of 0.5º lat/lon and temporal coverage between January 1901 and December 2010.

The FAO-56 Penman-Monteith's method is used for computing PET, instead of Thornthwaite in SPEIbase v1.0.

Unbiased probability weighted moments (ub-pwm) method is been used for fitting the log-Logistic distribution, instead of the sub-optimal plotting-position pwm method used in version 1.0.

The whole World is now stored in a single netCDF file. There one file for each time scale of the SPEI.
