The O<jats:sub>4<\/jats:sub> absorption profiles are inferred from direct Sun spectra observed from the LPMA\/DOAS (Laboratoire Physique Mol\u00e9culaire et Application\/Differential Optical Absorption Spectroscopy) balloon gondola. Seven O<jats:sub>4<\/jats:sub> absorption bands \u2010 centered at \u223c360.7, 380.2, 446.7, 477.1, 532.2, 577.2, and 630.0 nm \u2010 are investigated for atmospheric pressures (<jats:italic>p<\/jats:italic>) ranging from \u223c500 hPa to \u223c40 hPa and temperatures (<jats:italic>T<\/jats:italic>) ranging from 203 K to 250 K. For the encountered atmospheric conditions, it is found that, (a) the band shapes do not change with T and p and (b) the peak collision pair absorption intensities (\u03b1<jats:sub>i<\/jats:sub>) concurrently increase with decreasing T (by about 11 % over a \u0394<jats:italic>T<\/jats:italic>=50 K). That result is in agreement with previous laboratory O<jats:sub>4<\/jats:sub> studies mostly conducted at high O<jats:sub>2<\/jats:sub> partial pressures (up to several hundred bars). Furthermore, by reasonably assuming that the O<jats:sub>4<\/jats:sub> absorption cross sections are T\u2010independent, the inferred T\u2010dependence of \u03b1<jats:sub>i<\/jats:sub>(<jats:italic>T<\/jats:italic>) suggests a thermally averaged enthalpy change &lt; \u0394<jats:italic>H<\/jats:italic> &gt; = \u2212(1207\u00b183) J\/Mol involved in the formation of O<jats:sub>4<\/jats:sub>.
