Abstract

Abstract

Based on the oxonium ion chemistry, the NO density profiles in the low-latitude (28°38'N) upper D-region during a large solar flare are estimated. This method is valid for 80-87.5km where O⁺₂ has short lifetime and the negative ion density in comparison with positive ions can be neglected. It is found that the computed NO density profiles are in good agreement with Meira 's profile, but the minimum in 85 km is very weak.
