Lee, J.M., Sturges, W.T., Penkett, S.A., Oram, D.E., Schmidt, U., Engel, A. and Bauer, R. (1995). Observed stratospheric profiles and stratospheric lifetimes of HCFC-141b and HCFC-142b. Geophysical Research Letters 22: doi: 10.1029/95GL01313. issn: 0094-8276.

We present here the first stratospheric profile measurements of HCFC-141b (CH3-CFCl2) and HCFC-142b (CH3-CF2Cl). From the measurements we derive a stratospheric lifetime of 68¿11 years for HCFC-141b and an estimated minimum stratospheric lifetime for HCFC-142b of 138 years relative to an N2O lifetime of 110 y. (These results increase to 104¿17 y and >211 y respectively for an N2O lifetime of 168 y). Neither HCFC-141b nor HCFC-142b is now in equilibrium in the stratosphere, due to rapidly increasing emissions in recent years. ¿ American Geophysical Union 1995
