从1974年到1977年，用四丁基氢氧化铵浸渍过滤器在平流层取样了含有酸性溴的分子。采样由WB-57F飞机和高空气球完成，横跨纬度从赤道到北纬75度，高度达36.6公里。报告了4年测量和实验室模拟的分析结果，以确定若干溴化物种的过滤器收集效率。在平流层中收集到的空气中溴的质量混合比平均约为27pptm。季节变化似乎很小。参考文献16篇，图5张，表3张。
From 1974 to 1977, molecules containing acidic bromine were sampled in the stratosphere by using tetrabutyl ammonium hydroxide impregnated filters. Sampling was accomplished by WB-57F aircraft and high-altitude balloons, spanning latitudes from the equator to 75/sup 0/N and altitudes up to 36.6 km. Analytical results are reported for 4 years of measurements and for laboratory simulations that determine the filter collection efficiencies for a number of brominated species. Mass mixing ratios for the collected bromine species in air average about 27 pptm in the stratosphere. Seasonal variability seems to be small. 16 references, 5 figures, 3 tables.
