SCIAMACHY MISSION OBJECTIVES |
 |
|
|
 |
Tropospheric chemistry
|
|
|
Oxidizing capacity of the troposphere
|
|
|
Tropospheric photochemical ozone production and destruction
|
|
|
Tropospheric pollution (biomass burning, industrial pollution, aircraft emissions)
|
|
|
Characterization of the active photochemical environment in the troposphere
|
|
|
SCIAMACHY measures 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 measures 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 measures stratospheric profiles of O3, H2O, CH4, N2O, BrO and temperature fields, 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 measures 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 measures 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).
