Intercomparison of different remote sensing systems -: FTIR, DOAS and TDL

In summer 1998 a measurement campaign was performed at the lake Baldeney See in the south of the city of Essen in Germany. Two major goals should be achieved: First the intercomparison of several different remote sensing systems in real field measurements and second the determination of the ozone levels during summer with respect to the complex orographic and climatological situation of the lake Baldeney See which is intensely used as an recreational area. This paper refers to the results of the intercomparison of the remote sensing systems open-path FTIR, DOAS and TDL and presents a new automatic background generation routine for analyzing the FTIR spectra.
