Nitric Oxide Determination from Ionospheric Effects of Solar Flare in the Low-latitude Upper D-region

摘要: 通过氧鎓离子化学计算了一次强太阳耀斑扰动期间低纬度(28°38′N)D层顶NO浓度。该方法适用于O+2离子化学生存时间较短且负离子浓度与正离子相比可以忽略的80至87.5公里高度。计算结果表明,它相当好地符合Meira的实验观测剖面,只是85公里处的最小值特别弱。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.
