TRANSCRIPT

  • The Falcon 20 D-CMET

  • ENVISAT Validation activities of the Falcon 2 Different Missions with different Payloads and Objectives:

    SCIA-VALUE

    MIPAS-Val

    Main Objective

    SCIAMACHY level-2 data products:

    O3, N2O, NO2, BrO, ClO,

    H2O, OClO, and cloud and aerosol optical properties

    MIPAS level-2 products:

    H2O

    Campaigns

    2 Campaigns:

    Arctic to Tropics

    Sept. 2002, Feb. 2003

    1 Campaign:
