Determination of NO2 Photolysis Parameters for Stratospheric Modeling.

Abstract

This study was undertaken to obtain photolysis parameters for the presence of NO2 + hnu yields NO + O, which could be supplied to the modeling of that region. The absolute absorption coefficients for NO2 were measured at 297, 247, 226, and 204 K and are tabulated at 1-nm intervals over the 390-420 nm photolysis cut-off region. Experimental uncertainties range from 2% at room temperature at 420 nm to 15% at 204 K, and mainly fall in the 4-7% range.
