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))
