VERTICAL PROFILE MEASUREMENTS OF OZONE AT LAUDER, NEW-ZEALAND DURING ASHOE MAESA/

The Goddard Space Flight Center stratospheric ozone lidar was deployed at the National Institute for Water and Atmospheric Research (NIWA) f acility at Lauder, New Zealand (45 degrees S, 169 degrees E), during a ll four of the Airborne Southern Hemisphere Ozone Experiment/Measureme nts for Assessing the Effects of Stratospheric Aircraft (ASHOE/ MAESA) flight periods. The site is about 500 km south of Christchurch. Effor ts were made to acquire lidar data before dawn and after sunset on the days the ER-2 was flown. A total of 79 measurements were made on 47 i ndividual nights. Each measurement provided vertical profiles of aeros ols, temperature, and ozone. Profiles begin at similar to 8 km and ext end to 35, 50-55, and 75 km for aerosols, ozone, and temperature, resp ectively. NIWA personnel launched electrochemical concentration cell o zonesondes on a number of these occasions. A summary of these data wil l be presented along with comparisons with data from ER-2 instruments. Average profiles for each of the four ASHOE/MAESA deployments were co nstructed for use as a climatological profile for model initialization .
