Description:

This is the GPCC First Guess Daily Product of daily 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 daily totals for a month on a regular latitude/longitude grid with a spatial resolution of 1.0° x 1.0° latitude by longitude.
Interpolation is made for the daily relative quota of the monthly total, i.e., the daily total divided by the monthly total, the latter has the DOI:10.5676/DWD_GPCC/FG_M_100. The temporal coverage of the dataset ranges from January 2009 to the most recent month for which GTS based SYNOP data is available, i.e. the previous month, 3-5 days after its completion.

This GPCC product is recommended to be used when the timeliness of the precipitation information is of highest importance, e.g. for drought monitoring or climate watch similar to the (monthly) GPCC First Guess Product. In addition the GPCC First Guess Daily product allows to globally study extreme events and ralated statistics at daily resolution.
