Carbonyl sulfide (OCS) variability with latitude in the atmosphere
International audience Carbonyl sulfide (OCS) is an important precursor of sulfate aerosols and consequently a key species in stratospheric ozone depletion. SPIRALE and SWIR balloon-borne instruments have flown in the tropical region and in the Arctic polar region, and ground-based measurements have...

International audience Carbonyl sulfide (OCS) is an important precursor of sulfate aerosols and consequently a key species in stratospheric ozone depletion. SPIRALE and SWIR balloon-borne instruments have flown in the tropical region and in the Arctic polar region, and ground-based measurements have been performed by QualAir FTS instrument in Paris. Partial and total columns and vertical profiles have been obtained to study the OCS variability with altitude, latitude and season. The annual total column variation in Paris reveals a seasonal variation with a maximum in April-June and a minimum in November-January. Total column measurements above Paris and from SWIR balloon-borne instrument are compared with several MkIV measurements, several NDACC stations, aircraft, ship and balloon measurements to highlight the OCS total column decrease from tropical to polar latitudes.
