Observed Land Surface Precipitation Data: 1850-1995 (GISS/Dai)
Listed in NASA Earthdata CMR
[Source: NASA/GISS] The datasets here contain monthly and annual anomaly precipitation analyses.
Description
Dataset 1 covers the period 1900-1988, while the extended and updated Dataset 2 covers the period 1850-1995. Details of the analysis are described in the paper "Surface observed global land precipitation variations during 1900-1988" (Dai et al. 1997).
Following are a few major specifics: Anomalies are calculated relative to the 1951-1979 period. Values are in millimeters. Resolution of the longitude-latitude grid is 2.5° × 2.5°.

The center of grid cell (I,J) is at longitude (east) = -180.+(I-1)*2.5, latitude = -90.+(J-1)*2.5.
