Editor's Corner

Michael King, EOS Senior Project Scientist

Following up on my previous announcement that the Meteor 3M Stratospheric Aerosol and Gas Experiment (SAGE III) instrument was successfully launched on December 10, I'm pleased to report that SAGE III has completed all postlaunch calibration exercises, and is now routinely acquiring both sunrise and sunset occultation data. Preliminary analysis of Lunar Level 2 data products (NO2, NO3, and O3) indicates good agreement with profiles from LaRC's 2- dimensional atmospheric chemistry model. Overall, the instrument is performing as expected, albeit with high signal-to-noise ratio measurements. Additional refinement of the data is necessary due to the lack of GPS navigation data onboard the Meteor 3M Spacecraft. However, the SAGE III team is seeking support from the International Laser Ranging Service to provide satellite positioning information with sufficient accuracy to meet the instrument's retrieval processing requirements. SAGE III will extend important observations of aerosols, ozone, water vapor, and other important trace gases in the upper troposphere and stratosphere made by SAGE and SAGE II.

Similarly, the joint U.S./French Jason-1 mission that was successfully launched on December 7 has completed four cycles of mission operations and data collection, and is now producing its first operational science data products. Team managers from the French Space Agency's Satellite Control Center in Toulouse, France, and NASA’s Jet Propulsion Laboratory, Pasadena, CA, have declared Jason’s satellite, payload and...
