We are developing tomographic techniques for analyzing remote sensing observations of the coronal and heliospheric density and velocity structure as observed in Thomson scattering (e.g. by the SOHO/LASCO coronagraph and 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 co-rotating heliospheric structures and rapidly evolving events such as coronal mass ejections, as observed e.g. by the Helios photometers, and with 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 CMEs and other heliospheric structures at Earth.
