Abstract
In this field of research, we pursue the following objectives:
- Development and evaluation of methods for aerosol and trace gas detection using imaging spectroscopy or limb sounding instruments
- Application of the results in atmospheric correction algorithms
- Application of the results for the measurement of tropospheric constituents
- Intercomparison of ground and space based measurements
- Evaluation of quantification procedures using radiative transfer codes (MODTRAN, 6S, and others)
- Investigation of the relationship between topography and radiometric processing
Test data used for these studies were obtained with the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS), PHILLS/SAMSON, and MERIS on ENVISAT. Image scenes are preferred where due to strong topography and varying land cover varying ambient atmospheric regimes are expected.
