Retrieval of water vapor profile in the mesosphere from satellite ozone and hydroxyl measurements by the basic dynamic model of mesospheric photochemical system

摘要

We propose an indirect method for retrieving a number of significant minorgas constituents of the atmosphere. The technique is based on the use ofso-called basic dynamic models of atmospheric photochemical systemssimplified mathematically correctly in a special manner. It is applied to amesospheric system describing day evolution of key minor gas constituents atthese heights. We take as initial data experimental data of theCRISTA-MAHRSI satellite campaign of August 1997 during which ozone andhydroxyl (O and OH) concentrations were measured simultaneously. It isdemonstrated that the use of the basic dynamic model allows retrieval ofvertical distribution (within the 53–85 km range of heights) of water vaporconcentration that is one of the control parameters of the mesosphericphotochemistry.
