H2O, O3, N2O and HNO3 in the arctic stratosphere

The distribution of water vapor in the stratosphere

“…Should further evidence indicate that this data set (or any other) is in error, it will be a simple matter for the reader to recalculate his own average profile, omitting those results which are in doubt. Table 1 It is suggested that for modeling purposes, where fine structure variations in space or time are not required, the mean profile given in data set B of Table 1 Harries et al [1974]. Though the data are limited in quantity, there is little evidence overall to support the assumption that the dry conditions observed by Murcray are a permanent feature of north polar air.…”

Infrared Emission Spectroscopy

“…Some of the British and French studies of the atmosphere by far-infrared emission spectroscopy have been aimed at determining the environmental effects of the supersonic, high-altitude aircraft, Concorde. These studies were made during high-altitude tests of Concorde 001 and 002 (Marten et al, 1974;Harries et al, 1974;Harries, 1973). During a tour of the Far East made by Concorde 002 in June of 1972, spectra were recorded wherever possible in order to determine the global distribution of H N 0 3 , N 0 2 , N 2 0 , S 0 2 , H 2 0 , 0 2 , and 0 3 at the flight altitude which varied from 10 to 15 km (Harries, 1973).…”

“…Most of the emission spectra obtained since about 1970 from balloon or high-altitude aircraft have been measured in the far-infrared region below 150 cm" 1 (Clark and Kendall, 1976;Harries et al, 1976;Harries et al, 1974). An example of some recently reported results from a balloon experiment is shown in Fig.…”

“…Vertical mixing ratios of H 2 0 , 0 3 , N 2 0 , and H N 0 3 have been determined by Harries et al (1974) from spectra recorded aboard a Concorde flight above the Arctic Circle in May of 1973. The flight altitude was maintained constant at 15.25 km, and the limb-scanning technique was used to determine the concentration profiles.…”

Ecological problems of the earth's atmosphere

“…IV значения плотности двуокиси азота в нижней стратосфере находятся в грубом согласии с измерениями этой величины 40~42 . 70 . Совокупность процессов (4), (6), (13) При этом все процессы, кроме (13), приводят к переходам атомарного кис-лорода между окислами азота, а процесс (13) сопровождается гибелью атомарного кислорода и образованием молекулярного кислорода.…”
