GFZ GravIS RL06 Continental Water Storage Anomalies

GRACE/GRACE-FO Level-3 product based on GFZ RL06 Level-2B products (Dahle & Murböck, 2019) 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 containing 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.de).
