What is GENESIS?

GENESIS (Global Environmental & Earth Science Information System) is a suite of data services that bring together the Earth science products generated by spaceborne Global Positioning System (GPS) receivers flying on several international missions. GENESIS provides a database for GPS occultation observations from the CHAMP and SAC-C spacecraft, which carry NASA-supplied GPS receivers designed for atmospheric and ionospheric sounding. The flight database is augmented with GPS ground data and a variety of higher level derived products. We hope soon that occultation data from the GRACE mission can be added to this unique archive.

In the future, under NASA's REASoN (Research, Education, and Applications Solution Network) Program, GENESIS will expand its role to support more general Earth science investigations involving data from multiple flight instruments, providing specialized tools for mining, visualization, fusion, and analysis of large science data sets. A demo version of the new GENESIS will be available later this year.
