Latitudinal distributions of carbonyl sulfide (COS) over mid-high latitude in the Nothern Hemisphere
Concentrations of COS in the stratosphere and troposphere were determined from grab samples collected at altitudes ranging from 0.3–12 km during an aircraft flight over mid-high latitude in the Arctic Airborne Measurement Program 1998 (AAMP 98). Concentrations of COS in the troposphere were almost c...
