Project Summary

In 2007 I began an investigation of the near-surface energy and mass transfers using GRACE with GPS, MODIS and SSM/I datasets. I emplyee methods and techniques from satellite geodesy, geopotential theory and inverse (linear and non-inear) methods.

This webpage links to the data files held in the GIPL server "frosty" and to meta-data held at the IARC Data Archive.

An example from a movie of GRACE (GIA reduced) is shown below. The movie is at http://www2.gi.alaska.edu/~rmuskett/ (click GRACE NH Movie).
