Abstract
Stored air samples collected at Cape Grim, Tasmania since 1978, have been analyzed by GC-MS to investigate the change in the tropospheric concentration of HCFC-142b and HCFC-141b over the past 15 years. Between April 1978 and September 1993 the concentration of HCFC-142b rose, with the majority of this increase occurring from 1989 onwards. From 1989 to 1991 the average concentration of HCFC-141b was 0.08 ± 0.01 pptv. A very sharp increase in concentration began in 1992 however. Using a 2-D model of atmospheric chemistry, constrained by these observations, global emissions of these two compounds have been calculated and found to differ from other estimates. -from Authors
