Global Ionospheric Weather.
Abstract
We have studied several issues that are critical for understanding ionospheric weather. Work on global F region modeling has consisted of participation in the Phillips Laboratory Low Latitude Ionospheric Tomography Campaign, testing of the Global Theoretical Ionospheric Model (GTIM), and testing of the Parameterized Ionospheric Model (PIM). Analysis of TEC data and comparisons with other ionospheric models had been successfully conducted. A range of issues concerning the use of GPS observations have been studied. The topics have included limitations in determining TEC from dual-frequency GPS measurements, limitations to WAAS, solar cycle dependence of GPS TEC, and the statistics of time rate of change of TEC. Software has been developed to process RINEX formatted GPS data into TEC. Work comparing our electron- proton-H atom model to both observations and other models has been very successful. We have also successfully modeled the creation of polar cap patches and boundary blobs using time varying convection.
