Extended probabilistic climatology (EPC), as a reference forecast for precipitation in the tropics (Version 2)

Base dataset: Integrated Multi-satellitE Retrievals for GPM (IMERG) V06 dataset (doi: doi.org/10.5067/GPM/IMERG/3B-HH/06) Data format: netCDF Time resolution: daily (365 calendar days) Latitude band: 40°S–40°N Spatial resolution: 0.1°x0.1° (800x3600 points) Content: Parameters (prob, shape, scale) of a fitted Bernoulli-gamma distribution derived from +/-15 days windows around each calendar day of the years 2001–2018.

Value: The EPC dataset provides statistical distributions of daily rainfall for the entire global tropics with a high spatial resolution using one of the most accurate satellite-based rainfall estimates. This can be used for a climatological characterization and as a probabilistic reference forecast against which weather forecasts generated with computer or statistical models can be evaluated.
