Remote sensing measurements of total column amounts by spectroscopic techniques heavily rely on spectroscopic parameters for the target and interfering species, and on a priori vertical profile information. This paper discusses recent updates of O3 and NO2 datasets at the Jungfraujoch and Harestua primary and secondary NDSC (Network for Detection of Stratospheric Changes) stations, resp., from high-resolution EHR (Fourier Transform Infrared) and DOAS (Differential Optical Absorption Spectroscopy) UV/Visible observations. The former are direct-sun absorption measurements throughout the day under clear-sky conditions, the latter are zenith-sky scattered light measurements, daily at twilight. At the Jungfraujoch (ISSJ) the latter are performed with a SAOZ instrument since mid-1990; at Harestua, a home-made, NDSC-qualified instrument has been operated since 1993, on a more or less continuous basis. Two FTIR spectrometers, a Bruker IFS 120HR and a home-made FTS are operated on a regular basis at ISSJ; the FTIR database for NO2 starts in 1985.
