Abstract The investigation of infrared solar spectra recorded at the Interntional Scientific Station of the Jungfraujoch, Switzerland, with a high spectral resolution Fourier transform spectrometer, has revealed an absorption feature between 780.15 and 780.28 cm-1 which we have identified as the % MathType!MTEF!2!1!+-% feaafeart1ev1aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn% hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr% 4rNCHbGeaGGipm0dH8qqaqpepu0xbbG8F4rqaqFfpeea0x08pae9Lq% pepeea0xd9q8as0-LqLs-Jirpepeea0-as0Fb9pgea0lrP0xe9Fve9% Fve9qapdbaqaaeGaciGaaiaabeqaamaabaabaaGcbaGaamODaKaaGn% aaBaaajqwba9FaaKqzahGaaGinaaqcbawabaqefeKCPfgBaGqbcKaa% Gjaa-rbikiaadgfaaaa!40BA!\[v_4 ---Q\] branch of ClONO2 near 780.21 cm-1. While no details of the distribution versus altitude have been deduced from the data available so far, the analysis of June 1986 observations leads to a mean daytime column density of chlorine nitrate above the Jungfraujoch, equal to (1.15±0.3) E15 mol./cm2. This value is in good agreement with recently published ClONO2 results obtained during the ATMOS/SL3 mission at 30°N latitude. The present research represents an important step towards assessing the possibility of monitoring the telluric ClONO2 column density from high mountain based stations.
