The absorption cross‐sections of both O 2 , from 200 to 220 nm, and O 3 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 1'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 O 2 and O 3 cross sections have been found to meet most of the laboratory measurements. From 200 to 210 nm the results concerning the O 2 cross‐sections do not confirm the low values measured recently in the stratosphere and in the laboratory.
