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))
