Precision validation of MIPAS-Envisat products

Precision validation of MIPAS-Envisat products

This paper discusses the variation and validation of the precision, or estimated random error, associated with the ESA Level 2 products from the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS). This quantity represents the propagation of the radiometric noise from the spectra through the retrieval process into the Level 2 profile values. The noise itself varies with time, stea...

Validation of MIPAS-ENVISAT H2O operational data

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...

Interactive 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 ...
