Daily Observed Gridded Precipitation for Burkina Faso, Ghana, Benin and Togo from 1970 to 2009 in 0.1° x 0.1° Resolution

This gridded precipitation set is a test data set (BETA VERSION). The daily precipitation data set was created using a spatial interpolation technique using ordinary kriging. The gridded data set is based on 410 daily observed precipitation time series from stations located in Ghana, Benin, Togo, Burkina Faso and neighboring countries. They have been compiled from global (GHCN-daily), regional (e.g. AMMA-SYNOP, GLOWA-Volta) and national archives from the meteorological services of Burkina Faso, Ghana and Benin. The temporal coverage of the daily time series ranges from 1940 to 2013. The quality of the spatial interpolation was compared to various interpolation techniques (nearest neighbor, inverse distance and external drift kriging).
