Abstract

The stratospheric water vapor mixing ratio altitude profile has been derived from spectral observations of the downward night emission from the pure rotation water vapor lines in the 24-29-microm region of the spectrum. The data were obtained during two balloon flights, made on 22 February 1971 and on 29 June 1971, using a balloon-borne spectral radiometer with ~2 cm(-1) resolution. The observed radiances have been fitted to line-by-line, layer-by-layer radiance calculations, from which the water vapor mixing ratio between 10 km and 30 km has been flights show a broad minimum around of 6 x 10(-7)g/g to 4 x 10(-6) g/g.

摘要

平流层水汽混合比高度廓线是根据光谱24 - 29微米区域中纯转动水汽线的夜间下行发射光谱观测结果推导出来的。数据是在1971年2月22日和1971年6月29日的两次气球飞行中获得的，使用的是分辨率约为2厘米⁻¹的气球携带光谱辐射计。观测到的辐射亮度已逐线、逐层拟合到辐射亮度计算中，由此得出10公里至30公里之间的水汽混合比。飞行结果显示，在6×10⁻⁷克/克至4×10⁻⁶克/克左右有一个宽泛的最小值。
