Envisat 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 کاملRetrieval of Atmospheric Trace Constituents from Envisat Mipas Observations by Means of Rapid Radiative Transfer Calculations: First Results for Cfc-11
An optimal estimation retrieval approach has been applied to derive CFC-11 vertical profiles from Envisat MIPAS measurements. Rapid forward modeling during the retrieval process is based on well-tested approximative methods for the evaluation of the radiative transfer equation. We give a short description of the retrieval system, show an error analysis and discuss the global distribution of CFC...
متن کاملInteractive comment on “Envisat MIPAS
The paper reports the assessment of CFC-11 abundances in the stratosphere obtained using MIPAS observations in the first two years of operation. The retrieval of CFC-11 abundances from the measured radiances is obtained using an approximated and fast forward model. Even if yet limited to the two year for which consolidated MIPAS data are available, the analysis provides detailed information on ...
متن کاملValidation of Mipas-envisat Ch4, N2o, Cfc-11 and Cfc-12 by Airborne in Situ Observations
Airborne in situ measurements of the trace gases CH4, N2O, CFC-11 and CFC-12 with the High Altitude Gas AnalyzeR (HAGAR) on board the M55 Geophysica aircraft and the balloon-borne cryosampler BONBON of the University of Frankfurt are compared to vertical profiles from MIPAS-ENVISAT. We validate ESA level-2 standard products (v. 4.61) and non-operational trace gas profiles of CH4, N2O, CFC-11 an...
متن کاملThe MIPAS2D database of MIPAS/ENVISAT measurements retrieved with a multi-target 2-dimensional tomographic approach
We present a multi-year database of atmospheric fields of the upper troposphere, stratosphere and lower mesosphere retrieved from satellite measurements adopting a 2-dimensional tomographic approach. The full mission of the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) instrument, on board the European Space Agency ENVISAT satellite, is analyzed with the Geofit Multi-Target ...
