SCIAMACHY Mission Objectives in the context of current and future issues
in atmospheric chemistry
Tropospheric Chemistry
-
Oxidizing Capacity of the Troposphere
-
Tropospheric Photochemical Ozone Production and Destruction
-
Tropospheric Pollution (Biomass, Industrial Pollution, Aircraft)
-
Characterization of the active photochemical environment in the troposphere
SCIAMACHY will measure tropospheric columns of O3,
CO, CH4, N2O, NO2, SO2, HCHO,
H2O and the backscattered radiation field from 240 nm to 2380
nm (down to cloud top).
Stratosphere-Troposphere Exchange
-
Downward Transport of Stratospheric Ozone
-
Upward Transport of the Precursor Molecules (e.g. H2O, N2O
etc.) originating from the planetary boundary layer provides the feedstock
for ozone-destroying HOx, NOx and ClOx
radicals
SCIAMACHY will measure height resolved profiles of
the following tracers: O3, H2O, N2O and
CH4.
Stratospheric Chemistry and Dynamics
-
Monitoring of Stratospheric Ozone Depletion over Arctica and Antarctica
-
Monitoring of the Stratospheric Halogen Amount: The maximum stratospheric
halogen amount is expected around the turn of the century (WMO 95)
-
Global Ozone Budget, especially at midlatitudes
-
Test of Photochemical Modelling and Model prediction
SCIAMACHY will measure stratospheric profiles of
O3, H2O, CH4, N2O, BrO and
temperature fields, ClO and OClO under "ozone hole" conditions and the
backscattered radiation field, aerosol and cloud information.
Mesospheric Chemistry and Dynamics
-
Distribution of H2O and O3 and Global Circulation
-
Ozone Destruction due to Mesospheric and Stratospheric NO
SCIAMACHY will measure profiles of O3,
H2O, N2O, NO, O2 and O2(1Dg)
in the mesosphere
Climate
-
Monitoring of "Greenhouse" gases (e.g. O3, H2O, CO2,
CH4, N2O, CFC's.)
-
Monitoring of the radiation balance in the UV-NIR with high accuracy (incl.
cloud and aerosol information)
SCIAMACHY will measure the "Greenhouse" gases O3,
H2O, CH4, N2O, aerosol and cloud data,
surface spectral reflectance (320 nm - 2380 nm), the incoming and outgoing
SW flux, profiles of pressure and Temperature (via O2 and CO2)
