Space Weather: Construction of Web-based Empirical Models of the Earth's Ionosphere Using Data from Multiple Incoherent Scatter Radars

提出了使用8个非相干散射雷达(ISR)的数据建立三个综合的基于网络的电离层模型。这些模型将极大地扩展基于米尔斯通山ISR数据的最新模型。该模型将包括三个主要部分。前两个是北美和欧洲地区的基本和导出标量参数的模型，包括电子密度(Ne)、电子和离子温度(Te和Ti)、中性经向风和外层温度：第三个是EISCAT大陆雷达和VHF雷达获得的ExB等离子体漂移和相应的静电势模式。北美地区模型将基于Sondrestromfjord、米尔斯通山和阿雷西博ISR的数据。欧洲区域模式将基于EISCAT Svalbard、EISCAT大陆UHF和VHF、哈尔科夫和圣桑丁ISRS的数据。国家空间气象计划(NSWP)实施计划已将要模拟的参数确定为重要参数，必须根据客户的业务支持要求进行具体说明和预测。所有这些参数也被NSWP度量小组确定为第一、第二或第三优先参数，它们定义了电离层-热层(IT)系统的状态和条件。高纬度电场及其可变性也已被度量小组确定为IT系统的两个优先“驱动”参数之一。

Construction of three comprehensive web-based models of the ionosphere using data from eight incoherent scatter radars (ISRs) is proposed. These models will greatly extend recent models based on data from the Millstone Hill ISR. The model will include three main parts. The first two are North American and European regional models of basic and derived scalar parameters, including electron density (Ne), electron and ion temperature (Te and Ti), neutral meridional wind and exospheric temperature: the third is a model of the ExB plasma drifts and corresponding electrostatic potential patterns as obtained by the EISCAT mainland and VHF radars. The North American regional model will be based on data from the Sondrestromfjord, Millstone Hill and Arecibo ISRs. The European regional model will be based on data from the EISCAT Svalbard, EISCAT mainland UHF and VHF, Kharkov and St. Santin ISRs. The parameters to be modeled have been identified by the National Space Weather Program (NSWP) Implementation Plan as important ones which must be specified and forecast in response to customer operational support requirements. All of them have also been identified by the NSWP Metrics Panel as either first, second or third priority parameters which define the state and condition of the ionosphere-thermosphere (IT) system. The high-latitude electric field and its variability has also been identified by the Metrics Panel as one of two first priority "driver" parameters of the IT system.
