Abstract :
Ground-based millimeter wave observations of stratospheric trace gases have been carried out by IMK at the NDSC station Ny-Ålesund (78.9° N, 11.9° E) during March 1997. This measurement campaign was the authors contribution to the international intercomparison of chlorine monoxide (ClO) radiometers coordinated by IUP, University Bremen, during which 5 individual instruments have been installed at the same site. The radiometer of IMK has been operated continuously from 12 March to 31 March. Within this timespan there were coincident measurements in parallel with 1 or 2 of the other ClO radiometers on a few days, allowing a direct comparison of the measured spectra and the retrieved profiles. For the entire period the location was inside the polar vortex
