Space Weather: Accuracy of Ionospheric Models at Mid-Latitudes over Solar, Season, Diurnal, and Geomagnetic Variabilities: Implementation of Ionospheric Metric at CCMC

该项目将研究最先进的电离层模型（包括物理模型和经验模型）和国家空间天气计划（NSWP）电离层指标，利用从阿雷西博天文台过去30年观测得来的大量数据集。该数据集在季节变化和扰动条件下具有相当均匀的分布。本研究将利用整个阿雷西博非相干散射雷达（ISR）数据库，在国际参考电离层（IRI）、电离层预报模型（IFM）和耦合电离层热层等离子体电动力学（CITPe）三种模式上实现NSWP电离层指标。将开发软件，根据仪器性能、统计数据和电离层变异性自动选择ISR数据并产生定量观测不确定性。这个度量软件系统的主机将是美国宇航局戈达德太空飞行中心的社区协调模型中心（CCMC）。这项工作的最终结果将是为用户提供这些电离层模型的可靠度量评估。

The project will examine state-of-the-art ionospheric models (both physics based and empirical) and the National Space Weather Program (NSWP) ionospheric metrics, exploiting the large data set derived from Arecibo observations over the past 30 years. This data set has a reasonably uniform distribution over seasonal variations and disturbed conditions. This research will implement NSWP ionospheric metrics on three models, namely, the International Reference Ionosphere (IRI), the Ionospheric Forecast Model (IFM), and Coupled Ionosphere Thermosphere Plasmasphere electrodynamics (CITPe), using the entire Arecibo Incoherent Scatter Radar (ISR) database. Software will be developed to automatically select ISR data and generate quantitative observational uncertainties, based on instrument performance, statistics, and ionospheric variability. The host for this metric software system will be the Community Coordinated Model Center (CCMC) at NASA Goddard Space Flight Center. The end result of this effort will be to provide users with a reliable metric assessment of these ionospheric models.
