We report the results of measurements of five bromine‐containing trace gases (CBrClF 2 , CH 2 BrCl, CH 2 Br 2 , CH 2 BrCH 2 Br, and CH 3 Br) in the arctic during 1983 and during two of the spring 1983 AGASP aircraft flights. The results show that the anthropogenic bromine‐containing trace gases CBrClF 2 , CH 2 BrCl, and CH 2 Br 2 are more abundant during the winter or spring when arctic haze is observed. The same gases are also more abundant in the haze layers compared to their concentrations out of the haze as measured during the AGASP flights. The total bromine we measured in the arctic, however, appears to be only around 30 pptv, being about 10% more during spring when arctic haze is observed compared to the rest of the year.
