Title: A model of the neutral and ion nitrogen chemistry in the daytime thermosphere of Venus
Abstract: Density profiles of N( 4 S)NON(²D)NO + and N + are calculated for the thermosphere of Venus. The results show that N( 4 S) is the dominant odd nitrogen species throughout the thermosphere and has a maximum density of 1.8 × 10 7 atoms cm −3 at 132 km. The calculated NO + density agrees well with recent Pioneer Venus measurements but the calculated N + densities are a factor of two to five less than the measurements. The production of N( 4 S) atoms generated in the model is adequate to explain recent measurements of the nitric oxide chemiluminescent emission on the night side of Venus.
