AB: The Polar Ozone and Aerosol Measurement (POAM) III instrument has been making solar occultation measurements at polar latitudes in both hemispheres since April 1998. To date this data set comprises more than 32,000 high-resolution (1 km) vertical profiles of O3, NO2 and H2O density, as well as aerosol extinction from 350 to 1018 nm. In this paper we summarize the status of the POAM III validation analysis for all retrieved species. Using spatially and temporally coincident measurements, the POAM III retrievals are compared with data from other satellites (HALOE, SAGE II, SAGE III), as well as both in-situ and remote sensing aircraft- and balloon-based instruments, including a large sampling of high-latitude ozonesondes. These measurements have been obtained both in routine operation, and as part of special campaigns (e.g., SOLVE I and II). The comparisons provide a statistical estimate of the POAM III retrieval accuracy and precision. Results of this validation analysis are compared for consistency with estimated retrieval errors obtained from a formal error analysis. POAM III data are of high quality and are publicly available for scientific investigations and for validation of new and soon-to-be-launched satellite instruments.
