在过去的8年里，对瑞士Jungfraujoch国际科学站上方的氟化氢(HF)的数量进行了监测。从2.4 8μm附近的太阳红外吸收测量得到的光谱结果表明，2-4月期间的累积趋势相当于每年增加(8.5±1)%，以及与经向环流模式密切相关的短期变化。根据过去三年的强化测量，发现HF的综合含量经历了一个季节性的变化，最小值出现在秋季。从HF和HCl同时测量得出的HF/HCl比率在1977-79年期间为0.15，在1983-85年期间为0.24。
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 spectro-scopically from solar IR absorption measurements near 2.48 μm 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/HCl ratio derived from simultaneous HF and HCl measurements was found equal to 0.15 during the period 1977–79, and 0.24 for the 1983–85 timespan.
