MISSISSIPPI WATER STORAGE FROM GRACE

The combination of GRACE and in--situ data, a numerical hydrologic model, and the mathematical technique of 'data assimilation' permits to separate the total water content observed by GRACE into the various vertical components. See the Earth Observatory Summary for additional explanation.

More details in the papers by Rodell et al (2006) and Zaitchik et al (2008).
