✦ Synopsis

The amount of hydrogen fluoride (HF) above the International Scientific Station of the Jungfraujoch (Switzerland) has been monitored during the last 8 years. The results deduced spectroscopically from solar IR absorption measurements near 2.48 tim indicate a cumulative trend equivalent to (8.5 _+ 1)% increase per year, as well as short-term variability which appears to be strongly correlated with meridional circulation patterns during the February-April months. Based on intensified measurements made over the last three years, it is found that the integrated content of HF undergoes a seasonal change with a minimum occurring in the fall. The HF/HCI ratio derived from simultaneous HF and HCI measurements was found equal to 0.15 during the period 1977-79, and 0.24 for the 1983-85 timespan.
