Paper Abstract

The excitation mechanisms of 5577 angstrom auroral green line are studied using data from in situ rocket measurements by Sharp et al. and Deans and Chepherd. For the satisfactory agreement between modelled 5577 angstrom luminosity profiles and observed profiles during two experiments the rate coefficient of the quenching of O(1S) by O has to be equal to 1 (DOT) 10-11 exp(-680/T). Energy-dependent behavior of the column intensity ratio I5577 angstrom/I4278 angstrom is strongly varied with the season and can't be a good instrument for deducing initial electron flux parameters.
