First measurements of CFC-113 and HCFC-142b from space using ACE-FTS infrared spectra

[1] The first measurements of CFC-113 (CCl2FCClF2) and HCFC-142b (CH3CClF2) from space have been performed by the Atmospheric Chemistry Experiment (ACE), a satellite-based mission for remote sensing of the Earth's atmosphere. Retrievals for the volume mixing ratio profiles of these two molecules have been performed for ACE-FTS measurements at mid-latitudes and in the tropics, and the results are compared with AGAGE surface measurements. The agreement between ACE and AGAGE mixing ratios is within 15% for both CFC-113 and HCFC-142b.
