Abstract : The authors describe work involved in the analysis and modeling ionospheric data collected at various places around the globe. This involved correlation studies, regression analysis, fitting nonlinear time series and contour plotting. The authors helped develop a computer package for modeling the polar ionosphere. In addition, they prepared some efficient ray tracing programs, worked on problems for sunspot analysis, reduced and analyzed satellite measurements of electron densities in the ionosphere, and prepared theoretical and numerical solutions of electron transport characteristics in an irradiated solid.
