The working group "Radiation & Remote Sensing" (AG Strafern) emerged from the former Institute for Space Sciences (WEW). It works on ground-, airborne- and space-based remote sensing. The WG is invested in a wide array of fields of research among which are dust, aerosols, trace gaces (incl. water vapour), clouds and ocean colour. The group has two research aircraft as well as local infrastructure (incl. ground-based instruments, optic laboratories) at their disposal. Recently, the WG was integrated in the research network "Planetary systems, from the beginning to the natural habitat" at the Department of Earth Sciences of Freie Universität Berlin.
