Heating of the middle atmosphere as a result of quenching of the products of O2 and O3 photodissociation

The main product of O-2 photodissociation in Schumann - Runge continuum and in Ly alpha line and also O-3 photolysis in Hartley band is the excited atom of oxygen O(D-1). Electronic energy of this metastable level is redistributed at collisional and radiative processes in various channels. The suggested by us modem photochemical model of O-2 and O-3 photodissociation in the middle atmosphere includes in consideration transfer of electronic energy of atoms O(D-1) to electronic-vibrationally excited molecules O-2(b(1)Sigma(g)(+), vless than or equal to1) with the subsequent transfer of energy to the molecules O-2(a(1)Delta(g), vless than or equal to3). Except for it, we took into account formation of the molecules O-2(a(1)Delta(g), vless than or equal to5) in the ozone photolysis. The energy of O-2(a(1)Delta(g), vless than or equal to5) is transferred to the molecules O-2(a(1)Delta(g), vless than or equal to0) and further to the O-2(X(3)Sigma(g)(-), v) At all stages of energy transformation the radiative and collisional losses of energy are possible thus the part of energy thermalizes. The obtained results essentially differ from the previous model of energy transfer, in which the kinetics of electronic-vibrationally excited oxygen molecules were not considered.
