[49.10] 3-D Tomography of Interplanetary Disturbances

B.V. Jackson, P.P. Hick, A. Buffington (CASS/UCSD)

We are developing tomographic techniques for analyzing remote sensing observations of heliospheric density and velocity as observed in Thomson scattering (e.g. by the Helios photometers) and interplanetary scintillation (IPS) observations.

We have refined the program to enable us to analyze time-dependent phenomena, such as the evolution of corotating heliospheric structures and rapidly evolving events such as coronal mass ejections. We intend our analyses to be used with data from the future Solar Mass Ejection Imager (SMEI) experiment. We currently provide these analyses in real-time using IPS observations in order to forecast the arrival of corotating structures and CMEs at Earth.
