Retrieval of chlorofluorocarbon distributions from Envisat MIPAS measurements

摘要

A retrieval processor based on rapid forward modeling algorithms and an optimal estimation approach has been developed at Forschungszentrum Juelich, Germany. It has been used to derive global distributions of the chlorofluorocarbons CFC-11 and CFC-12 from Envisat MIPAS measurements. We give a detailed description of the retrieval system, show error analyses, and discuss briefly the seasonal behavior of CFC-11 and CFC-12 for January to March and July to September 2003.
