Solar irradiance in the stratosphere: Implications for the Herzberg continuum absorption of O sub(2)

The third Solar Absorption Balloon Experiment performed measurements of the attenuated solar irradiance between 200 and 210 nm as the payload ascended from 32 to 39 km. Comparison of these data with calculations based on ozone and pressure measurements made from the payload shows more solar radiatio...

Summary:The third Solar Absorption Balloon Experiment performed measurements of the attenuated solar irradiance between 200 and 210 nm as the payload ascended from 32 to 39 km. Comparison of these data with calculations based on ozone and pressure measurements made from the payload shows more solar radiation reaching the middle stratosphere than is predicted by O sub(2) and O sub(3) cross sections which are widely used in photochemical modeling. Consideration of the uncertainties in the balloon data and laboratory experiments indicates that the discrepancy can best be removed by adopting Herzberg continuum cross sections for O sub(2) which are equal to or slightly less than the smallest values which have appeared in the literature.
