About NOAA CFSR / CFSv2
The Climate Forecast System Reanalysis (CFSR, 1979–2011) and its operational successor CFSv2 (2011–present) are NCEP's coupled atmosphere-ocean-land-sea ice reanalysis products, distributed by NOAA NCEI at roughly 0.2°–0.5° resolution and sub-daily timestep. The ocean coupling gives it an edge for coastal and estuarine studies where sea-surface conditions feed back into the atmospheric forcing.
Access is via NOAA's NOMADS THREDDS server or FTP archive in GRIB-2 format — less turnkey than ERA5's CDS API, but a useful third reanalysis for basins where ECMWF and NASA products disagree.
