Joint CHAMP/GRACE Science Meeting
Four years after the launch of the CHAMP satellite and more than two years after successfully placing the GRACE satellite pair into orbit a first joint meeting of the CHAMP and GRACE Science Teams was held on July 6-8, 2004 at the GeoForschungsZentrum Potsdam (GFZ).
The meeting stimulated a broad discussion within the international science community on the exploitation and application of the gravimetric, magnetic and atmospheric data products from these highly innovative geodetic missions in low altitude orbits. It also demonstrated the CHAMP/GRACE mission data potential for Earth system science studies when being used in combination with data from complementary remote sensing missions, aircrafts and ground instrumentation.
