Space Weather: Short-Term Forecasting of Plasma Structure Development in the Equatorial Ionosphere

PI将开展一项为期三年的计划，以发展对赤道电离层传播扰动的短期预报能力。 具体来说，他将解决在夜间赤道电离层等离子体结构的发展的日常变化。 这将通过一个跨越磁倾角赤道的电离层台站的赤道链来实现。 这条链将能够同时测量两个半球的等离子体密度分布作为高度和倾角纬度的函数。 此外，中性风的测量将是不必要的。 该项目的具体目标是：（1）同时测量作为高度和倾角纬度的函数的等离子体密度分布，沿着两个半球中的磁子午线，（2）在ESF发展期间测量两个半球中的共轭E区特征，（3）使用两个半球中的测量来评估ESF发展的前兆特征，（4）对各种短期预报方法进行综合检验;（5）测量夜间ESF发展的纵向相关性。

The PI will conduct a three-year program to develop a short-term forecasting capability for propagation disturbances in the equatorial ionosphere. Specifically, he will address the day-to-day variability in the development of plasma structure in the nighttime equatorial ionosphere. This will be accomplished with a meridional chain of ionospheric stations that spans the magnetic dip equator. This chain will enable simultaneous measurements in the plasma-density distribution as a function of altitude and dip latitude in both hemispheres. Moreover, measurements of the neutral wind will not be necessary. Specific aims of the project are: (1) simultaneously measure the plasma-density distribution as a function of altitude and dip latitude, along a magnetic meridian in both hemispheres, (2) measure conjugate E-region characteristics in both hemispheres during the development of ESF, (3) evaluate the precursor signature for ESF development using measurements in both hemispheres, (4) perform comprehensive tests of various short-term forecasting methods, and (5) measure the longitudinal correlation of nightly ESF development.
