SAMMOA-FTIR

Updated 2002-02-13

The FTIR (Fourier Transform Infrared Spectroscopy) has been established as a powerful tool for measurements of atmospheric trace gases. Using the sun or moon as light source, between 20-30 trace gases of the tropo- and stratosphere can be detected by their absorption features. The analysis of the spectra allow to retrieve the total zenith columns of the trace gases. The aim of the SAMMOA project is to study the stratospheric ozon depletion during the summer time period. While the processes during winter/spring are investigated in detail the summertime ozone loss has not been studied so far. Therefore FTIR solar absorption measurements of ozone and related species are to be done on much more observation days beside the routine observations within the NDSC
