Data requirements to use: None;
Data used: Mean temperature data are obtained from the NOAA NCEP CPC GHCN_CAMS gridded dataset. Monthly precipitation sums data are obtained from the Global Precipitation Climatology Centre (GPCC). Data from the 'first guess' GPCC product, with an original resolution of 1º, are interpolated to the resolution of 0.5º. Currently, the SPEI Global Drought Monitor is based on the Thortnthwaite equation for estimating potential evapotranspiration, PET. ;
Data format: netcdf;
Data access: website;
Concise description:
The SPEI Global Drought Monitor offers near real-time information about drought conditions at the global scale, with a 0.5° s spatial resolution and a monthly time resolution. SPEI time-scales between 1 and 48 months are provided. The calibration period for the SPEI is January 1950 to December 2010.
The dataset is updated during the first days of the following month based on the most reliable and updated sources of climatic data.
Indices included:
SPEI-1, SPEI-3, SPEI-6, SPEI-9, SPEI-12, SPEI-24, SPEI-36, SPEI-48
