COMPARISON OF STRATOSPHERIC OZONE PROFILES AND THEIR SEASONAL-VARIATIONS AS MEASURED BY LIDAR AND STRATOSPHERIC AEROSOL AND GAS EXPERIMENT DURING 1988

A ground-based, high power, laser remote sensing system for measurements of stratospheric ozone concentration profiles has been in operation at the Jet Propulsion Laboratory Table Mountain Facility located in southern California, +34.4°N, -117.7°W, since January 1988. The seasonal variations observed in the ozone profiles, during 1988 and as a function of altitude, are described here. These profiles are compared with those from the Stratospheric Aerosol and Gas Experiment (SAGE II) satellite instrument made within a radius of 1000 km from the lidar and also with the zonal mean measurements made in the band 34.4° ± 5°. Comparison with the proposed new CIRA ozone reference model has also been carried out. The seasonal variations, between 25 km and 50 km, observed by the two instruments and indicated by the reference model are in good agreement. -Authors
