| Summary: | ABSTRACT/RESUME Ground based Fourier Transform Infrared (FTIR) measurements have been performed at the Arctic Station of Ny-Ålesund, at the mid latitude site Bremen, as well as on board the German research vessel ‘Polarstern’. Additionally, aerosol and ozone lidar measurements were conducted and ozonesondes have been launched at Ny-Ålesund. Here, we give an overview of the data recorded so far, and show first comparisons of the data with Sciamachy products. 1 FTIR MEASUREMENTS For the validation of the Sciamachy instrument, measurements with three FTIR spectrometers have been performed. These measurements provide high resolved absorption spectra of the atmosphere, using the sun or the moon as a light source. Generally, the total columns of more than 20 different trace gases can be retrieved from these data. Additionally, in case sufficiently high resolved spectra are recorded, height resolved information with a coarse resolution of 6-8 km can be obtained for a subset of these molecules. 1.1 Ny-Ålesund In Ny-Ålesund (78.92 N, 11.93 E), FTIR measurements have been performed since 1992 [1], and in the same year the site was accepted as a primary station within the NDSC (Network for Detection of Stratospheric Change). The instrument used is a Bruker 120 HR spectrometer. |
