Global Monthly Precipitation, 1900-1999 (Hulme)


An historical monthly precipitation data set for global land areas from 1900 to 1998 has been constructed from over 11,880 station time series. The data have been gridded at two different resolutions (2.5 degrees latitude by 3.75 degrees longitude and 5 degrees latitude/longitude) and are available for use in scientific research.

A documentation file accompanies each data file and contains details about the source data, gridding method, data format, and conditions of use.
