Dear Colleagues;


The purpose of the message is to inform you of the release of the first Grace Gravity Model.  The details of the model, as well as the model coefficients, can be found at the following web sites:


        http://www.csr.utexas.edu/grace/
        http://www.csr.utexas.edu/grace/gravity/


and
        http://www.gfz-potsdam.de/grace/
        
Since the mission is still in the cal/val phase, we would value your assessment of the models as input for improving future model release.


Sincerely,


Byron Tapley and Christoph Reigber
