Validation of SAGE III - ISS Ozone with NOAA OMPS and Ground -based Instruments in the Context of Prior Satellites

Résumé

SAGE III (Stratospheric Aerosol and Gas Experiments) on ISS has provided limb measurements of ozone profiles since late 2017. SAGE III joins its predecessors SAGE I (1979-1981), SAGE II (1984-2005) and SAGE III Meteor-3M (2002-2005) which are often the backbone of several merged ozone profile data records and associated trend studies such as discussed in the SPARC/LOTUS [2018] report. The focus of this study will be on long-term stability. The increasing duration of the measurements opens the opportunity for review of instrument stability. This effort will additionally characterize the compatibility of SAGE III ISS with SAGE II using SBUV/2 and OMPS and available ground-based instruments as transfer standards. SBUV/2 measurements are available from the NOAA Polar Orbiters from 1978 to present, measuring nearly globally with 15 orbits per day. The OMPS Nadir Profiler (NP) on Suomi-NPP and NOAA-20 provide a follow on to SBUV with similar measurement traits. The vertical resolution of the SBUV/OMPS is smoothed as compared to the SAGE Limb, but abundant coverage of the NOAA satellites provides good opportunity for frequent comparisons. NOAA's ground-based instruments (GB) include vertical distribution of ozone from Dobson Umkehr and ozonesonde profiling with a long record. Microwave and lidar datasets from NDACC additionally provide opportunities to study the compatibility of the SAGE III instruments. Microwave specifically allows the exploration of the diurnal properties of SAGE as seen with sunrise/sunset sampling.
