Spectro-polarimetric experiments for remote sensing
WG4 Meeting in Helsinki, 19-21 August 2013
Polarized light reflectance measurements are essential to empirically validate physically-based parameterization, to verify selected theoretical models, to provide ground reference data for the calibration of remote-sensing observations, and to support databases needed for data-analysis techniques. Exploitation of acquired experimental information is a valuable tool in target classification and quantification.
In the frame of the proposed workshop we invite researchers conducting reflectance measurements or using the measurement data. The primary focus is on the polarimetric characterization of test sites and targets, covering also angular, spatial and spectral aspects. Measurement techniques, modelling, and other use of measurement data can also be discussed, where related to polarimetric experiments. It is expected, that the workshop could lead to the organization of future joint measurement campaigns, raise a number of important applications and suggest novel retrieval algorithms by combining measured data obtained from different sensors.
