Simulated STEREO views of the Solar Wind following the CMEs of 1 August 2010

The images observed by twin spacecraft STEREO A and B appear as complex structures for two coronal mass ejections (CMEs) on August 1, 2010. Therefore a series of sky maps of Thomson-Scattered white Light by ICMEs on August 1, 2010 are simulated using the Hakamada-Akasofu-Fry (HAF) three-dimensional solar wind model. Comparison between the simulated sky maps and observations of STEREO A and B clarifies the structure and evolution of interplanetary CMEs (ICMEs) and corotating interaction regions (CIRs) in the observed images. Results demonstrate that the simulated sky maps by the HAF model are very useful in the interpretation of the observed images when the ICMEs and CIRs overlap or extend beyond the fields of view of the instruments onboard STEREO A and B. In addition, the multiple spacecraft allow parameter adjustments leading to significant improvements in model performance.
