Medium-scale traveling ionospheric disturbances (MSTIDs) are wave-like variations in ionospheric density and altitude that are widely observed from high to low latitudes. This project addresses questions of their origin and evolution by carrying out multi-site, multi-instrument investigations and applying tomographic reconstructions. The project will include outreach activities to students and the public in Puerto Rico. The tomographic technique will enable a deeper understanding of the electrodynamics of MSTIDs by creating wide area maps of the field-line integrated Pedersen conductivity independent of magnetic-field geometry. The following questions regarding the three-dimensional airglow structure will be addressed: (1) How does MSTID structure relate to the spatial/temporal distribution of field-line integrated Pederson conductivity? (2) Is MSTID plasma transport dominated by neutral winds or electrodynamics?

中尺度电离层行波扰动（MSTID）是电离层密度和高度的波动，广泛存在于高纬度到低纬度地区。该项目通过进行多地点、多仪器调查和应用层析重建来解决其起源和演变问题。该项目将包括面向波多黎各学生和公众的外联活动。 层析成像技术将使更深入地了解电动力学的MSTIDS创建广域地图的磁场线集成彼得森电导率独立的磁场几何形状。以下问题有关的三维气辉结构将被解决：（1）如何MSTID结构涉及的空间/时间分布的场线集成Pederson电导率？(2)MSTID等离子体输运是由中性风还是电动力学主导的？
