Extant, nested instrumentation at the Arecibo Observatory is augmented by supply of an imaging system capable of all-sky, mesoscale, or local fields-of-view. This instrument is to become a community accessible resource at Arecibo, and is here focused on studies of the triggering mechanisms of F-region irregularities. Simulations of generalized Perkins instabilities using measured ionospheric and thermospheric boundary conditions are used to compare triggering theory with observations. The research goals are to isolate irregularity seeding mechanisms, to classify instability structure evolution, and to determine the role of horizontal gradients (in state variables) in the generation of irregularities - while providing a broadly useful research instrument to the community at-large.

阿雷西博天文台现有的嵌套仪器通过提供具有全天空、中尺度或局部视场的成像系统而得到增强。 该工具将成为阿雷西博社区可访问的资源，重点研究 F 区异常现象的触发机制。 使用测量的电离层和热层边界条件对广义珀金斯不稳定性进行模拟，用于将触发理论与观测结果进行比较。 研究目标是分离不规则性播种机制，对不稳定结构演化进行分类，并确定水平梯度（状态变量）在不规则性生成中的作用，同时为整个社区提供广泛有用的研究工具。
