• 2 Different Missions with different Payloads and
  Objectives

SCIA-VALUE(SCIAMACHY Validation and Scientific
Utilisation Experiment)
Objectives Validation of SCIAMACHY level-2
data products O3, N2O, NO2, BrO, ClO, H2O,
OClO, and cloud and aerosol optical properties

instruments ASUR, AMAXDOAS, and OLEX for
air-borne validation of SCIAMACHY data products
O3, N2O, NO2, BrO, ClO, H2O, OClO, and cloud and
aerosol optical properties

MIPAS-VAL

• Objectives
• The measurement of water vapour and aerosol
  profiles using the airborne H2O-DIAL of DLR as
  the core instrument and the comparison of these
  data to the respective MIPAS Level 2-products.
• Intercomparison with the remote and in-situ
  GEOPHYSIKA instruments measuring water vapour and
  aerosol (i.e. MIPAS-STR,SAFIRE-A, FISH, FLASH,
  MAL, MAS, FSSP, ABLE)
• Measurement of small-scale structures in the
  tropopause region, the comparison of these
  results with the ENVISAT products and model
  results of climate and climate-chemistry models.
• Campaign
• Joint campaign with the GEOPHYSIKA mid-latitude
  validation activities (Forli, Italy (October
  2002))
