Dear Colleagues,
It is my pleasure to announce we have processed the first atmospheric
occultation profiles from the GRACE satellite.
Please check the GENESIS web site for more information:
http://genesis.jpl.nasa.gov
I would like to thank everybody on the GPS Earth Observatory team at
JPL for their participation in this successful first test of the GPS
occultation capability onboard GRACE. Thanks also to the GRACE team
for scheduling and operating the test. We are very encouraged by the
results and look forward to exciting scientific contributions from
the GRACE GPS occultation experiment.
GPS Earth Observatory Team at JPL:

Larry Young
Special Thanks to:
Willy Bertiger
Gerhard Kruizinga
Da Kuang
Additional comments courtesy of George Hajj:
The retrieval is completely independent of any model (we initialize
the hydrostatic at 50km, with T=245K). Note the interesting sharp
structure near the tropopause missed by the model (occultation number
1).
Sincerely,
Tony Mannucci
