New in-situ measurements of the absorption cross-sections of O 2 in the Herzberg Continuum

Abstract : The absorption cross-sections of both 02, from 200 to 220 nm, and 03 from 220 to 235 nm have been deduced from measurements of the atmospheric absorption performed at night aboard a stratospheric balloon launched from Aire sur l'Adour (France). The ozone column content was previously determined using the absorption measured from 278 to 289 nm, assuming that the ozone absorption cross sections are well known in this wavelength interval. The 02 and O_ cross sections have been found to meet most •f the laboratory measurements. From 200 to 210 nm the results concerning the 02 cross-sections do not confirm the low values measured recently in the stratosphere and in the laboratory.
