Mesure de l'absorption stratosphérique du rayonnement solaire de 3,05 à 3,70 microns

Abstract

Solar spectra have been recorded from 3.05 to 3.70µm by means of a balloon borne monochromator at an altitude of 35 km and for solar zenith distances from 75° to 95°. Absorptions due to CH4 and H2O are identified as well as 03 bands observed for the first time in the atmosphere. Upper limits for the stratospheric mixing ratios of NO2 and HCHO are deduced.
