Abstract

GRACE/GRACE-FO Level-3 product based on COST-G RL01 Level-2B products (Dahle & Murböck, 2020) representing Terrestrial Water Storage (TWS) anomalies provided at 1° latitude-longitude grids as defined over all continental regions except Greenland and Antarctica. The TWS anomaly grids are provided in NetCDF format divided into yearly batches. The files each contain four different variables:

1) 'tws': gravity-based TWS
2) 'std_tws': gravity-based TWS uncertainties
3) 'leakage': spatial leakage contained in TWS
4) 'model_atmosphere': background model atmospheric mass

These Level-3 products are visualized at GFZ's web portal GravIS (https://gravis.gfz-potsdam.de). Link to data products: ftp://isdcftp.gfz-potsdam.de/grace/GravIS/COST-G/Level-3/TWS
