The product is based on monthly COST-G RL02 GRACE/GRACE-FO Level-2B Products ( Meyer et al., 2025, doi: 10.5880/COST-G.ICGEM_02_L2) provided at 0.5° latitude-longitude grids as defined over all continental regions. The TWS anomaly grids are provided in NetCDF format, containing three different variables:

1) 'twsa': gravity-based terrestrial water storage anomaly
2) 'std_twsa': gravity-based terrestrial water storage anomaly standard deviations
3) 'flag_filter': Flag indicating the filter strength


File History:

The Copernicus Climate Change Service (C3S) groups its datasets into Climate Data Records (CDRs), representing major version releases, and Intermediate Climate Data Records (ICDRs), which only extend the existing data and do not involve any processing changes.
