IDENSO: Ionospheric Dynamics over Eritrea from Nightglow and Scintillation Observations

双站GPS接收器数据提供了小规模（400米分辨率）的全球定位卫星（GPS）无线电闪烁和非洲厄立特里亚上空等离子体消耗漂移的测量。630nm全天空成像同时提供了f区消耗的大尺度背景。这些数据是在1999年至2003年的四年期间获得的，用于研究赤道扩展- f不规则的形成、形态和日常变化。将这些非洲数据同化到全球模式中，独特地限制了人们对这些不规则现象的知之甚少的气候学，这些不规则现象已知会破坏通信和导航。

Twin-station GPS receiver data provide, on small scales (400 m resolution), a measure of Global Positioning Satellite (GPS) radio scintillations and plasma depletion drifts above Eritrea in Africa. Large-scale context of F-region depletions is provided simultaneously by 630 nm all sky imaging. These data, acquired during a four-year period from 1999 - 2003, are used to investigate the formation, morphology, and day-to-day variability of the equatorial spread-F irregularity. Assimilation of these African data into global models uniquely constrains the poorly understood climatology of these irregularities that are known to disrupt communication and navigation.
