Comparison of In situ Observation, NOAA-AIRS Satellite and MACC Model on Surface Ozone Over the Ushuaia, Southern Ocean and Antarctic Peninsula Region M.S.M. Nadzir, M.F. Khan, W. Suparta and S.K. Zainudin Abstract This study aims to determine surface ozone (O 3 ) mixing ratios from in situ observations during the Malaysian Antarctic Scientic Expedition Cruise 2016 (MASEC16), by using The Monitoring Atmospheric Composition and Climate (MACC) global model assimilation system developed by the European Centre for Medium-Range Weather Forecasts (ECMWF) and satellite products from the National Oceanic and Atmospheric Administration-Atmospheric Infrared Sounder (NOAA-AIRS) over the Antarctic Peninsula region. We also compared all three types of observation of surface O 3 during the period of MASEC16. The results showed that surface O 3 levels from MACC reanalysis and NOAA-AIRS were twice higher than those from in situ observations over Ushuaia, the Drake Passage (Southern Ocean) and the Antarctic Peninsula respectively. Nevertheless, the surface O 3 mixing ratios pattern from MACC and NOAA-AIRS were similar to the in situ measurements where mixing ratios of the surface O 3 were in the order of Ushuaia < Southern Ocean < Antarctic Peninsula meaning that the NOAA-AIRS satellite and MACC model products are likely to be effective proxies for atmo- spheric composition over a given region.
