GEM Workshop on Intercalibrationg Cusp Signatures

第一次GEM(地球空间环境模型)理论观测活动解决了磁层顶、边界层及其在电离层尖端的特征问题。1989年10月在马里兰大学举行的观测讲习班的与会者确定，该运动的第一项任务应是通过与航天器粒子数据相互校准地面和机载设施直接飞越的情况，确定地面和机载数据中的尖点特征。来自航天器仪器的相对容易识别的尖点粒子签名将作为破译下面签名的罗塞塔石头。为此，1990年1月16日在黑点附近进行了一项试点数据收集计划，许多小组正在收集档案数据进行相互校准。这笔赠款是为一个研讨会提供的，以便将这些数据汇集在一起进行分析和理论解释。

The first GEM (Geospace Environment Modelling) theory- observing campaign addresses problems of the magnetopause, boundary layers, and their signatures in the cusp of the ionosphere. Participants in the observing workshop held last October 1989 at the University of Maryland determined that the first task of the campaign should be the confident identification of cusp signatures in ground-based and airborne data by intercalibrating with spacecraft particle data on direct overflights of the ground-based and airborne facilities. The relatively easily recognized cusp particle signatures from the spacecraft instruments would serve as a Rosetta stone for deciphering signatures below. To this end, a pilot data- gathering program took place in the vicinity of the dark cusp on January 16, 1990, and many groups are gathering archival data for intercalibration. This grant is for a workshop to bring these data together for analysis and theoretical interpretation.
