Climate Hazards Group InfraRed Precipitation with Station Data-Prelim (CHIRPS-Prelim)

The Climate Hazards Center InfraRed Precipitation With Station Data-Prelim (CHIRPS-Prelim) is a blend of CHIRPS data with in situ precipitation data to unbias the data and enhance its accuracy. The process of generating CHIRPS- Prelim is similar to the CHIRPS process, with the main difference being its reliance on Global Telecommunication System (GTS) stations only, which are available in near-real time. Blending of CHIRP with GTS-only stations allows for the latency of CHIRPS- Prelim to be <5 days. Note that, in general, the differences in CHIRPS-Prelim and CHIRPS are within acceptable limits, as both data sets share the same climatological mean. You can find additional information here and on climate org dataset page here.

This dataset is to be used in conjunction with CHIRPS Pentad/Daily collections, which are Earth Engine assets at: - UCSB-CHG/CHIRPS/PENTAD
