CMIP5 Standardized Precipitation Evapotranspiration Index data

Standardized Precipitation Evapotranspiration Index (SPEI):

• SPEI results should be interpreted as a relative measure of surface water surplus or deficit with respect to hydroclimate conditions of the reference period, 1950–2005.
• The data are available at a 1x1 degree grid resolution for the landmass of Canada at 1, 3 and 12 month time scales.
• Please see the technical notes for more information on the development and use of the SPEI dataset.
