This proposal will improve short-term forecasting of equatorial spread-F (ESF) by the correlative analysis of radar and ionosonde measurements made at Pohnpei, Micronesia and Christmas Island, Kiribati, two equatorial locations separated by about 44.5 degrees longitude (about three local solar hours) in the central Pacific. This proposal addresses prediction of the onset of ESF and the resulting radio-wave scintillation that can severely impact satellite communication and navigation systems. It focuses on investigating the reliability of potential precursors for ESF onset and on the spatial-temporal coherence of these precursors. These new radar measurements will be of considerable importance for investigating ESF in support of the Air Force's upcoming C/NOFS satellite mission, and will provide a valuable new data set for the space weather research community.

这一建议将通过对密克罗尼西亚波恩佩和基里巴斯圣诞岛这两个位于中太平洋的赤道位置的雷达和电离层探测仪测量结果进行相关分析，改进赤道扩展F（ESF）的短期预报。该建议涉及对可能严重影响卫星通信和导航系统的ESF开始和由此产生的无线电波闪烁的预测。它侧重于调查的可靠性潜在的前兆ESF发病和这些前兆的时空一致性。这些新的雷达测量将是相当重要的调查ESF在支持空军即将到来的C/NOFS卫星使命，并将提供一个宝贵的新的数据集空间天气研究界。
