This paper describes the first results of measurements with the new sensor module FUBISS-Polar. The system measures hyper spectral polarimetric sky radiances in the spectral range from 250 to 1080 nm at four different polarization angles (0°, 45°, 90°, 135°) and enables the calculation of the degree of the linear polarization (DOLP) and its azimuth. This paper will give an overview of the instrument and the data calibration procedures and will present the first results of measurements taken at the laboratory and at three different field campaigns. The field campaign measurements were done in the principle plane of the sun during clear sky conditions in arctic environments (Ny Alesund, Svalbard), on top of the mountain Zugspitze (Alps, Germany) and in urban environments (Berlin, Germany).
