Download climate/weather data from the Copernicus Climate Data Store (CDS) using the CDS API. Use this skill whenever the user wants to download ERA5, ERA5-Land, seasonal forecasts, or any other CDS dataset. Also use it when the user mentions CDS, Climate Data Store, ECMWF reanalysis, cdsapi, .cdsapirc, or asks about downloading climate/weather reanalysis data — even if they don't say "CDS" explicitly. Covers: writing efficient download scripts, choosing the right dataset, configuring API access, optimizing request splitting, and selecting data formats (NetCDF vs GRIB).
