The investigator, a CEDAR post-doctoral awardee, develops an empirical global ionospheric electric field model, using all available incoherent scatter radar ion drift measurements and some satellite observations. His model includes longitudinal, latitudinal, altitudinal, seasonal, solar cycle, and geomagnetic variations of the ionospheric electric field, and extends from equatorial to high latitudes from the E to the upper F region. High, mid and low latitude results are extended to lower altitudes by theoretical model results. Mid, low and equatorial electric field perturbations include prompt penetration electric fields from high to low latitudes, and electric field effects of the ionospheric disturbance dynamo. The model significantly improves and extends existing global empirical electric field models, and also provides realistic electric field estimates for applying global ionospheric electric field distribution.

该研究员是CEDAR博士后获奖者，利用所有可用的非相干散射雷达离子漂移测量和一些卫星观测数据，开发了一个经验性的全球电离层电场模型。 他的模型包括电离层电场的经度、纬度、高度、季节、太阳周期和地磁变化，并从赤道延伸到高纬度，从E区到F区。 高、中、低纬度地区的数值模拟结果被理论模式推广到低海拔地区。 中、低和赤道电场扰动包括从高纬度到低纬度的瞬发穿透电场和电离层扰动发电机的电场效应。 该模型对现有的全球电离层电场经验模型进行了改进和扩展，为应用全球电离层电场分布提供了现实的电场估计。
