Ground Based FTIR Measurements of O3, HF, HCl, ClONO2, and HNO3 at Kiruna (Sweden) since Winter 1993/94

Abstract. Zenith column amounts of O3, HF, HCl, ClONO2, and HNO3 have been measured at Kiruna within the polar vortex. Chlorine activation has been detected during all winters since 1993/94, except of 1998/99. Low HNO3 to HF ratios as observed in February 1995 and 1996 indicate denitrification.
