GPCC First Guess Product at 1.0°: Near Real-Time First Guess Monthly Land-Surface Precipitation from Rain-Gauges based on SYNOP Data

This is the GPCC First Guess Product of monthly global land-surface precipitation based on the station database (SYNOP) available via the Global Telecommunication System (GTS) of the World Meteorological Organization (WMO) at the time of analysis (3 - 5 days after end of the analysis month). This product contains the monthly totals on a regular latitude/longitude grid with a spatial resolution of 1.0° x 1.0° latitude by longitude. Interpolation is made on the anomalies from the GPCC Climatology V2015 in the corresponding resolution (DOI: 10.5676/DWD_GPCC/Clim_M_V2015_100). The temporal coverage of the dataset ranges from August 2004 until the most recent month for which GTS based SYNOP data is available, i.e. the previous month, 3-5 days after its completion.
