Global Hdo Measurements with Mipas
We have used high spectral resolution spectroscopic measurements from the MIPAS instrument on the Envisat satellite to simultaneously retrieve vertical profiles of H2O and HDO in the stratosphere and uppermost troposphere. A thorough error analysis of the retrievals confirms that reliable δD data can be obtained up to an altitude of 45 km. Averaging over multiple orbits and thus over longitudes...
متن کاملGlobal and regional emission estimates for HCFC-22*
HCFC-22 (CHClF2, chlorodifluoromethane) is an ozone-depleting substance (ODS) as well as a significant greenhouse gas (GHG). HCFC-22 has been used widely as a refrigerant fluid in cooling and air-conditioning equipment since the 1960s, and it has also served as a traditional substitute for some chlorofluorocarbons (CFCs) controlled under the Montreal Protocol. A low frequency record on troposph...

متن کاملEnvisat MIPAS measurements of CFC-11: retrieval, validation, and climatology
From July 2002 to March 2004 the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) aboard the European Space Agency’s Environmental Satellite (Envisat) measured nearly continuously mid infrared limb radiance spectra. These measurements are utilised to retrieve the global distribution of the chlorofluorocarbon CFC11 by applying a new fast forward model for Envisat MIPAS and an ac...
متن کاملMeasurement and Validation of Hydrochlorofluorocarbon-22 from the Mipas Instrument
Our retrievals of HCFC-22 vertical profiles volume mixing ratios (vmrs) from MIPAS-E spectral data are presented. Using a retrieval scheme developed at the University of Leicester we have detected a mean global enhancement of HCFC-22 vmrs compared to 1998 values. Latitudinal variations of HCFC-22 concentrations are also detected. A preliminary validation of our HCFC-22 retrievals is presented w...
