Evolution of stratospheric temperature structure in a marine environment: Comparison of lidar and GPS occultation retrievals near Hawaii
Robert Farley, The Aerospace Corp., Los Angeles, CA; and G. S. Peng and J. E. Wessel
An intercomparison of atmospheric temperature retrievals from CHAMP and SACC GPS satellite occultations with coincident ground-based lidar measurements by the Aerospace Transportable Lidar System (ATLS) is presented. GPS occultations provide globally distributed snapshots of atmospheric parameters, while ground-based lidar provides accurate high temporal and spatial resolution measurements, but from a fixed location. Results from a recent January campaign conducted in Hawaii during which both types of instruments detected significant medium to large-scale stratospheric wave activity are analyzed. The character and evolution of these disturbances as revealed by these diverse systems and ancillary balloon sonde measurements will be discussed.
