The Diurnal Variation of the Neutral Sodium Species in the Upper Atmosphere. A Model Study.

Abstract

A study is made to calculate the diurnal behavior of the neutral sodium species (Na, NaO, NaO2, and NaOH) in the mesosphere using a one-dimensional photochemical model. The calculated results for Na are compared with available observations. The model results show that NaO2 is an important reservior for the sodium species in the atmosphere, and that the diurnal variation of Na in the mesosphere is, to a large extent, determined by the diurnal behavior of atomic oxygen. The role of NaOH as a temporary reservior for sodium and its possible effect on stratospheric chlorine chemistry remains unclear, as there is insufficient information from observation of Na to determine the rate for the atmospheric production of NaOH.
