Geospace Plasma Dynamics Laboratory Annual Task Report (FY11).

摘要

This annual report provides a summary of progress made during FY11 on AFOSR task titled 'Geospace Plasma Dynamics.' The goal of this research effort is to develop a detailed knowledge of the space environment by analyzing satellite data and developing the theories needed to explain the observations. In this way we hope to improve our capability to predict the state of the space environment. This effort includes 4 basic research efforts. They are 1) Investigate the spatial and temporal evolution of the turbulent field-aligned Birkeland current system, 2) Investigate solar wind-magnetosphere-ionosphere coupling processes, 3) Specify and predict long-term (3 day) forecast of the low-latitude ionosphere using first principles models, and 4) Investigate the physics of penetration electric fields.
