CORRELATIVE STRATOSPHERIC OZONE MEASUREMENTS WITH THE AIRBORNE UV DIAL SYSTEM DURING TOTE VOTE/

The airborne UV differential absorption lidar (DIAL) system participat ed in the Tropical Ozone Transport Experiment/Vortex Ozone Transport E xperiment (TOTE/VOTE) in late 1995/early 1996. This mission afforded t he opportunity to compare the DIAL system's stratospheric ozone measur ing capability with other remote-sensing instruments through correlati ve measurements over a latitude range from the tropics to the Arctic. These instruments included ground-based DIAL and space-based stratosph eric instruments: HALOE; MLS; and SAGE II. The ozone profiles generall y agreed within random error estimates for the various instruments in the middle of the profiles in the tropics, but regions of significant systematic differences, especially near or below the tropopause or at the higher altitudes were also found. The comparisons strongly suggest that the airborne UV DIAL system can play a valuable role as a mobile lower-stratospheric ozone validation instrument.
