About cdsapi (Copernicus CDS)

cdsapi is the official Python client for the Copernicus Climate Data Store, which serves ERA5 — the global reanalysis that has become hydrology's default gap-free climate record — along with seasonal forecasts, CMIP projections, and dozens of derived datasets. A short script with your API key downloads exactly the variables, levels, period and region you need.

For catchments with sparse gauge coverage (most of the world), ERA5 via cdsapi is frequently the difference between "no forcing data" and a runnable model. Free registration; generous quotas; queue times vary.
