気球高度における大気 H_2O スペクトルの観測

概要

Far-infrared H_2O emission spectra of the upper atmosphere have been obtained during a balloon flight in Alice Springs, Australia. Analyses show that the emission features of the telluric H_2O are fitted by a model atmosphere of 245K in mean temperature and of 1.7×10^<18>cm^<-2> in H_2O column density. We have also made an assessment for the telluric H_2O absorption via this model, thus anabling a correction of the observed astronmical spectra.
