Summary of Data Held: Monthly precipitation observations
are regularly exchanged world-wide for about 4,500 stations, in
synoptic and CLIMAT messages via the WMO World Weather Watch Global
Telecommunication System (GTS). These GTS-data are complemented
by other international data collections (NOAA/NMC and FAO) up
to world-wide 6,700 stations, which is the basis for the GPCP/GPCC
interim land-surface precipitation grid. The Center has designed
and operates a data processing system with the following functions:
- collect and archive monthly precipitation data world-wide
- quality control these data
- calculate a real mean totals on the basis of the conventional
measurements over land
- merge these analyses with precipitation estimates from other
observational techniques (e.g., satellite images), or from mode
simulations in order to obtain global precipitation data sets
- determine the error range of the analysis results
Data Products, Publications, Catalogs: The GPCP/GPCC
interim product for the earths land-surface precipitation, available
on a grid of 2.5 by 2.5 degrees latitude by longitude for the
period from January 1986 onwards. These results are available
as digital gridded datasets via ftp as as well as on floppy diskettes
including software for display of maps. Global products based
on the terrestrial raingauge products combined with satellite
observations and numerical weather forecasts will be available
by end of 1996.
