Spectroscopic observations of the total column amount of hydrogen chloride above an altitude of 12 kilometers in the latitude range 20 degrees to 40 degrees N have been made both before and 3 to 6 months after the eruptions of El Chichón Volcano in March and April 1982. In the region of the cloud of volcanic aerosols, the hydrogen chloride total column after the eruptions increased by approximately 40 percent, even after allowance is made for the global secular increase in hydrogen chloride of 5 percent per year. The column amounts of hydrogen fluoride show no such increase.
对 1982 年 3 月和 4 月埃尔奇琼火山喷发前后，北纬 20 度至 40 度之间 12 公里以上高空的氯化氢总量柱进行了光谱观测。在火山气溶胶云区，即使考虑到全球每年氯化氢增加 5%的长期趋势，喷发后氯化氢总量柱仍增加了约 40%。氟化氢总量柱没有显示出这种增加。
