Coordinated ground-based validation of ENVISAT atmospheric chemistry with NDSC network data : Commissioning phase report

Abstract

International audienceIn the framework of the coordinated project called CINAMON, a list of ground-based stations associated with the Network for the Detection of Stratospheric Change (NDSC) contribute to the quasi-global validation of ENVISAT atmospheric chemistry data. This paper reports on such activities performed during the Commissioning Phase (CP) of the satellite. After a description of the correlative database generated during this period, preliminary ground-based studies relying on this database give a first picture of the quality of SCIAMACHY ozone and nitrogen dioxide columns, and GOMOS and MIPAS ozone profiles. Illustration of the global mapping of MIPAS ozone profile data is also presented. The paper concludes with perspectives for the Main Validation Phase of ENVISAT
