Helper masks for global soil-moisture data (Copernicus)

CLMS SWI Static Global 12.5km V3
hydrosphere ESA ESA Copernicus COGNetCDF
In plain English

What it measures. This is not a measurement layer itself but a set of static reference masks and supporting files that go with the global Soil Water Index products.

How it's made. ESA Copernicus provides these auxiliary files alongside the ASCAT-based Soil Water Index series at 12.5-kilometre spacing.

How & where you'd use it. A behind-the-scenes input: analysts use it to correctly read and interpret the daily, 10-daily, and time-series soil moisture data, not for standalone results.
