List of data provided

---------------------------------------------------

The dataset contains timeseries (1988-2020) of annual precipitation anomalies from

- observation (GPCP)

- reanalysis (ERA5)

- multi-model mean (CMIP6)

GPCP is the Global Precipitation Climatology Project.

ERA5 is the fifth generation ECMWF (European Centre for Medium-Range Weather Forecasts) atmospheric reanalysis of the global climate.

CMIP6 is the sixth phase of the Coupled Model Intercomparison Project.
