HeliosphericTomographySMEI (1)

Model Description

A new Heliospheric Tomography model developed for Solar Mass Ejection Imager (SMEI) (The Air Force/NASA instrument, launched January 6 2003) is now available at CCMC. SMEI is a joint project of University of California San Diego, Boston College, the University of Birmingham (UK), and the Air Force Research Laboratory. SMEI is recording whole sky data on each 102-minute orbit.

The 3-D reconstruction technique incorporates a kinematic solar wind model and tomographically fit this to SMEI Thomson scattering brightness observations (Jackson et al., 2008). The SMEI time-dependent tomography provides densities at nearly three-times better resolutions in space and time than the IPS. The SMEI analysis allows the 3-D reconstruction of CMEs and other heliospheric structures such as corotating interaction regions (CIRs). The SMEI analysis incorporates IPS velocities when these data are available, and allows their presentation along with density.
