In August 2023, the Canadian-led Atmospheric Chemistry Experiment (ACE) mission will complete its 20th year in orbit on board the SCISAT satellite. The long lifetime of ACE provides a valuable time series of composition measurements that contribute to our understanding of ozone recovery, climate change and pollutant emissions. The main instruments on board SCISAT use infrared and UV-visible...
Since the mid-1980s, a series of limb and occultation instruments provide observations to assess past and recent changes in stratospheric ozone. Long-term changes are so small that the stability of the ozone profile climate data records (CDRs) must be better than ~2% per decade in order to be detected. Ensuring this level of stability poses a challenge for the teams providing datasets of...
We report the results of validation exercise of ozone and temperature L2 MIPAS products, processed with IMK/IAA Level 2 scientific processor. Ozone profiles are compared to ACE-FTS, MLS, GOMOS, OSIRIS and SAGE II records, as well as to ozonesondes records from HEGIFTOM database.
Temperature profiles are compared to ACE-FTS, MLS and HALOE satellite records, GRUAN profiles, and COSMIC and...
