A parameterization for absorption due to the A, B, and γ oxygen bands
Abstract
A new parameterization for the absorption of visible solar radiation due to O2 is presented. This broad band parameterization is based on comparison with detailed line-by-line calculations and is shown to be in excellent agreement with laboratory measurements. The importance of solar O2 absorption to atmospheric heating rates and temperatures is also discussed. Although the heating caused by the solar O2 bands is small (<0.03 K day-1), its presence warms the tropical tropopause region by as much as 1.1 K. Finally, the importance of correct asymptotic limits for modeling the absorptance of O2 is illustrated.
