IPS 3 D Velocity and Density Analysis Summary: IPS analysis: This ground-based technique can provide low-resolution velocity and density analysis, and accurate forecasts of time-variable heliospheric structure. Other ground-based analyses such as heliospheric Faraday rotation can possibly be provided from the same radio systems. The IPS analysis can provide input to 3 D-MHD models. Better, and more abundant IPS data, should be available from world IPS systems in the near future. CASS/UCSD AFOSR 2014
