Description
MSWEP stands for Multi-Source Weighted-Ensemble Precipitation and is a global precipitation product with a 3‑hourly 0.1° resolution available from 1979 to ~3 hours from real-time. The product is unique in that it merges gauge, satellite, and reanalysis data to obtain the highest quality precipitation estimates at every location.
MSWEP incorporates daily gauge observations and accounts for gauge reporting times to reduce temporal mismatches between satellite-reanalysis estimates and gauge observations. MSWEP is compatible with GloH2O’s operational Multi-Source Weather (MSWX); MSWX forecasts can thus be used to extend MSWEP into the future. MSWEP tends to exhibit better performance than other precipitation products in both densely gauged and ungauged regions (see the Performance section here, Beck et al., 2017, and Beck et al., 2019 - see references).
We offer data of years 1979-2020 of version v2.8 of the data set. Data are provided by the original data set provider with ~3 hour latency (see https://www.gloh2o.org/mswep)
The data set was made available at ICDC: June 15, 2023
