The monthly mean precipitation is taken from the gridded climatology data base developed by New et al. (1999) for the climatic normal period of 1961-1990. This data set includes weather-station data from all over the world and interpolated monthly precipitation data based on an innovative approach to correct for local differences in elevation between stations.

	Monthly mean precipitation
	unit: mm/month dimension: month

The monthly mean precipitation is taken from the gridded climatology database by New et al. (1999) for the climatic normal period of 1961-1990. They have collected weather-station data from all over the world and interpolated the monthly precipitation data using an innovative approach to correct for local differences in elevation between stations.

We use this database as our baseline climatology for the precipitation patterns on which the precipitation change is overlaid.

The climatic patterns are used in the terrestrial vegetation model to calculate vegetation and crop patterns and productivities, in the terrestrial carbon model to calculate the different carbon fluxes, and in the land-use emissions model to calculate emissions.
