Abstract

We report the first long-term analysis of the total column of ClONO₂ from groundbased infrared solar absorption measurements recorded at Lauder, New Zealand. Between September 1990 and August 1994 the ClONO₂ total column averaged 1.22(±0.4)×10¹⁵cm^-2, in good agreement with previous airborne and spaceborne measurements at southern hemisphere midlatitudes. The monthly mean ClONO₂ column over Lauder shows a clear seasonal cycle with a peak amplitude of 22(±3)% of the yearly mean with the seasonal maximum occurring in early September. This is the first measured seasonal variation of ClONO₂. -from Authors
