摘要

摘要提出了一个考虑等离子体化学过程、双极扩散以及电磁漂移和中性风引起的平流离子输运的地球电离层F区(100-500 km)全球动力学模型。该模型包括磁层对流引起的极电场的参数化和简化的赤道漂移考虑。本文的重点是描述电离层模型中开发和使用的具体方法。概述了全球电离层特征形成的关键过程，并对其在模型中的表示进行了评估。该模型充分再现了全球电离层的主要特征，如季节周期和日周期、赤道电离异常(EIA)、极地电离帽和主槽。

INM-IM: INM RAS Earth ionosphere F region dynamical model

Abstract A new INM RAS global dynamical model of Earth’s ionosphere F region (100–500 km), which takes into account plasma-chemical processes, ambipolar diffusion, and advective ion transport due to electromagnetic drifts and neutral wind is presented. The model includes parameterizations of polar electric fields induced by magnetospheric convection and simplified equatorial drifts considerations. The focus of the paper is directed on the description of specific methods developed and utilized in the ionospheric model. Key processes responsible for the formation of global ionospheric features are outlined and their representation in the model is evaluated. The main global ionospheric characteristic features, such as seasonal and diurnal cycles, the equatorial ionization anomaly (EIA), polar ionization caps and the main trough have been adequately reproduced based on this model.
