Abstract

In frame of building up the high-altitute environmental research station Zugspitze/Schneefernerhaus a measurement system for the investigation of trace gases on the basis of FTIR spectrometry is developed. A spectrometer with a spectral reolution up to 0.0014 cm^-1 is the main part and first solar absorption spectra will be shown. Complementary a transportable spectrometer at spectral resolutions 0.06 cm^-1 was used in the last years. These spectra are interpreted by the SFIT software package to retrieve atmospheric column densities of HCl, HF, N₂O, O₃, H₂O, HNO₃, and other gases. The results will be discussed in connection with spatial and temporal atmospheric variations.
