AB: Results of the HIRDLS ozone validation effort made to date are presented here. Comparisons of the latest corrected ozone retrievals are made with solar occultation measurements, AURA/MLS, ozonesondes, and airborne and ground-based lidar. An unanticipated large visual obstruction in the HIRDLS field-of-view presented major challenges to the data analysis methods and implementation, as detailed in Gille, et al., this session. An extended intensive effort was made to characterize the radiative properties of the obstruction and to correct measured radiances accordingly. The HIRDLS ozone compared here are retrieved from these corrected radiances. Comparisons indicate that HIRDLS ozone is recoverable, with precision of largely better than 5 percent and with a high vertical resolution. Precision, accuracy and vertical resolution of HIRDLS ozone measurements will be highlighted. Correction algorithm development is continuing and some additional improvement is anticipated. HIRDLS will be able to meet its ozone measurement design criteria.
