Measurements and Applications
Polarimeter for measuring aerosol optical properties, clouds and aerosol types. Multi-angle spectro-polarimetry by spectral modulation technology. Distribution and detailed micro-phyiscal properties of atmospheric aerosol. Direct and indirect aerosol radiative forcing and their impact on climate. A second instance of this instrument is in development.
