TOVAS Update: Global Precipitation Climatology Centre (GPCC) Monitoring Data

The Global Precipitation Climatology Centre (GPCC) global precipitation monitoring product is a monthly 1° x 1° product produced by the Deutscher Wetterdienst (DWD, National Meteorological Service of Germany) under the auspices of the World Meteorological Organization (WMO).

GPCC has now changed its analysis scheme, using its new global gridded monthly precipitation climatology for the analysis background. Based on this new analysis scheme, all GPCC monitoring analyses from January 2007 to present have been reanalysed and named GPCC Monitoring Analysis Version 2, according to the GPCC. We have updated TOVAS (http://disc2.nascom.nasa.gov/Giovanni/tovas/ground.GPCC.shtml) to reflect this change.
