Description : | Spatio-temporal variations of the continental water storage (water + snow mass) inverted from monthly or/and 10-day solutions of GRACE (Gravity Recovery And Climate Experiment) satellite mission. Units : mm of equivalent-water height. Spatial resolution : Maximum harmonic degree 50 (about 400 km at the surface of the Earth). |
Coverage : | Global. |
Duration : | April/May 2002 - End of 2005. |
Source : | GOHS Team of LEGOS (OMP, Toulouse, France). |
Data available on request. Contact Guillaume Ramillien. | |
Documentation : | Principles of the inverse method applied to GRACE geoids is provided in the following article : |

Format : | 3-column monthly files in ASCII (longitude, latitude, equivalent water height) or lists of corresponding spherical harmonic coefficients. |
