Seasonal variations of atmospheric trace gases in the high Arctic at 79 degrees N
Since March 1992 the total column abundances of several tropospheric and stratospheric trace gases have been monitored year-round from the Network for Detection of Stratospheric Change station in Ny Alesund, Spitsbergen (78.9 degrees N, 11,9 degrees E). A groundbased Fourier transform infrared (FTIR) spectrometer performed these measurements using the Sun as a light source during the summer, and t
