The fluorocarbon and nitrous oxide content of the stratosphere have been studied as a function of altitude, latitude, and time. Whole air samples have been gathered from a balloon platform, primarily through use of a cryogenic sampler. Twenty‐two flights were conducted between 1975 and 1980, and gas chromatography was utilized to determine species mixing ratios in the retrieved samples. Results are evaluated in terms of various stratosphere models.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
