ECCO V4r4 (LLC90) grid geometry and January 2010 3D volume fluxes — subset for open-source software example notebooks

A small, unmodified subset of NASA's ECCO Version 4 Release 4 (V4r4) ocean state estimate, redistributed here only to make example notebooks for open-source software like sectionate reproducible without an Earthdata login. Files (native Lat-Lon-Cap 90 grid; 13 tiles × 90 × 90, 50 levels): GRID_GEOMETRY_ECCO_V4r4_native_llc0090.nc — time-invariant grid geometry (coordinates, cell metrics, bathymetry, hFac partial-cell fractions, land/ocean masks). Source: ECCO Geometry Parameters for the Lat-Lon-Cap 90 (llc90) Native Model Grid (Version 4 Release 4), DOI 10.5067/ECL5A-GRD44. OCEAN_3D_VOLUME_FLUX_mon_mean_2010-01_ECCO_V4r4_native_llc0090.nc — one monthly mean (January 2010) of mass-weighted velocities UVELMASS, VVELMASS, WVELMASS. Source: ECCO Ocean Three-Dimensional Volume Fluxes – Monthly Mean llc90 Grid (Version 4 Release 4), DOI 10.5067/ECL5M-3VF44. The only processing applied was selecting one month (January 2010) from the full 1992–2018 monthly series; data values are byte-for-byte identical to the PO.DAAC originals, and all original NetCDF global attributes (including source DOIs) are preserved.
