Advances in Observation, Modeling, and Forecasting of Ionospheric Plasma Irregularities
Session ID#: 82028
Session Description:
Plasma density irregularities are a persistent feature of the Earthâs ionosphere at all latitudes. The generation, morphology and dynamics of irregularities are intimately linked to plasma instabilities and physical processes that couple the ionosphere to the magnetosphere, solar wind, and neutral atmosphere. Multiscale characterization of irregularities and resolution of the mechanisms that govern irregularity generation and evolution continue to be unsolved scientific problems. New and innovative data analysis and modeling techniques (e.g. machine learning) have the potential to address some of these outstanding issues. This session will be a forum for discussing recent advances in regional-and-global observation, simulation, modeling, and forecasting of irregularities that occur over a range of scales, from microscale scintillation-producing structures to macroscale (continental-size) disturbances. Submissions that include the development of forecasting and mitigation tools for the degrading impact of irregularities on GNSS and communication systems are also of significant interest.
