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

提出了利用八个非相干散射雷达（ISR）的数据构建三个全面的基于网络的电离层模型。 这些模型将极大地扩展基于Millstone Hill 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基本和衍生标量参数的区域模型，包括电子密度（Ne）、电子和离子温度（Te和Ti）、中性经向风和外逸层温度：第三个是ExB等离子体漂移模型和EISCAT大陆和甚高频雷达获得的相应静电势模式。 北美区域模型将以Sondrestromfjord、Millstone Hill和Arecibo ISR的数据为基础。 欧洲区域模型将基于EISCAT斯瓦尔巴特群岛、EISCAT大陆UHF和VHF、哈尔科夫和St. 国家空间气象方案（NSWP）实施计划已经确定了要建模的参数，这些参数是必须根据客户业务支持要求进行规定和预测的重要参数。 所有这些参数也都被NSWP电离层-热层小组确定为确定电离层-热层系统状态和条件的第一、第二或第三优先参数。 高纬度电场及其可变性也被评估小组确定为信息技术系统的两个首要“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.
