Title Remote-sensing studies of heliospheric solar-wind structure around two solar minima
Abstract Remote-sensing observations of the inner heliosphere are carried out routinely using both the interplanetary scintillation (IPS) observations of astronomical radio sources and also the Thomson-scattered white light from heliospheric electrons. For these latter observations, we use the Earth-orbiting Solar Mass Ejection Imager (SMEI: from February 2003) aboard the Coriolis Satellite, and more recently using the Heliospheric Imagers (HIs) aboard the Solar TErrestrial RElations Observatory twin spacecraft (STEREO: from late 2006/early 2007). The data sets from various IPS-capable systems as well as SMEI are used with the University of California, San Diego (UCSD) three-dimensional (3-D) tomographic-reconstruction and visualisation algorithms. We are able to compare with {\it in-situ} measurements from multiple spacecraft with these reconstruction results. This makes it possible to study the structure of the inner heliosphere as a whole, including the isolation of individual features or events such as interplanetary coronal mass ejections (ICMEs) or stream interaction regions (SIRs). We look at the global structure of the heliosphere during the current and previous solar minima, and discuss similarities and differences between the two solar cycles where possible.
