This SGER award will allow the PI to take advantage of the immediate availability of a 50 MHz radar on Christmas Island (CXI) (Republic of Kiribati) to conduct a two-radar experiment to explore whether the development and characteristics of irregularities in the nighttime equatorial F region (known as equatorial spread F, or ESF) are correlated in longitude and time. The other radar, located on the island of Pohnpei (Federated States of Micronesia), is already in continuous operation, and data from measurements taken by that radar will be made available at no cost to the proposed effort.Besides information about the timescales associated with the source process for ESF development, the database of backscatter plumes over two locations is expected to provide further insight into the source of ESF plume characteristics. Each data set will also provide, for the first time, descriptions of the seasonal and longitudinal dependences of ESF activity in those longitude sectors. The findings of this investigation are expected to pave the way toward developing a short-term forecasting capability for ESF development, a prime objective of the National Space Weather Program.

该SGER奖将使PI能够利用圣诞岛（CXI）（基里巴斯共和国）上立即可用的50 MHz雷达进行双雷达实验，以探索夜间赤道F区域（称为赤道扩展F或ESF）的不规则性的发展和特征是否与经度和时间相关。另一个雷达位于波恩佩岛（密克罗尼西亚联邦），已经在连续运行，该雷达测量的数据将免费提供给拟议的努力。除了与ESF开发源过程相关的时间表信息外，在两个位置上的后向散射羽流数据库有望提供对ESF羽流特征的来源的进一步了解。每个数据集还将首次提供ESF活动在这些经度部门的季节性和纵向依赖性的描述。这项调查的结果预计将铺平道路，为ESF的发展，国家空间气象计划的主要目标，发展短期预报能力。
