Meteoric Metals and Noctilucent Clouds: An Experimental Study of the Uptake of Sodium and Potassium Atoms on Low-Temperature Ice Films

Abstract

This report results from a contract tasking University of East Anglia as follows: The Grantee will investigate the kinetics of atomic Na and K uptake on both amorphous and cubic crystalline ice films, over the temperature range 100 to 150 K. The data obtained will be used in a predictive, high resolution 1-dimensional model of the upper mesosphere. Model predictions will be validated by comparison with lidar observations of the depletion of Na and K layers during the formation of noctiluscent clouds. The results of the kinetic studies and model validation will then be published and will be provided to AFRL personnel for inclusion in mesospheric background codes.
