The Climate Hazards Center (CHC), based at the University of California, Santa Barbara, provides open-access climate datasets focused on rainfall monitoring and drought early warning. Their most widely used product is CHIRPS (Climate Hazards Group InfraRed Precipitation with Stations), which combines satellite observations with station data to produce high-resolution precipitation estimates over land.
CHC datasets are distributed as publicly accessible files (e.g. GeoTIFF and NetCDF) and do not require authentication or a dedicated API. Data are accessed directly via HTTP and can be streamed for spatial subsets.
The dhis2eo.data.chc module contains convenience functions for accessing selected CHC datasets and returning results as xarray objects for downstream analysis. See:
