Abstract

The photodissociation coefficient of NO2, JNO2, has been measured from a balloon platform in the stratosphere. Results from two balloon flights are reported. High Sun values of JNO2 measured were 10.5±0.3 and 10.3±0.3×10-3 s-1 at 24 and 32 km respectively. The decrease in JNO2 at sunset was monitored in both flights. The measurements are found to be in good agreement with calculations of JNO2 using a simplified isotropic multiple scattering computer routine.
