Title Current and Planned Solar Wind Observations Using the EISCAT and LOFAR Radio-Telescope Systems
Abstract Remote-sensing observations of the inner heliosphere using the technique of interplanetary scintillation (IPS) provide essential information on the velocity and density of developing solar wind structure. For many years, observations of IPS have been undertaken with the European Incoherent SCATter (EISCAT) radio telescopes based across Northern Scandinavia. We are presently developing the IPS experiment for use on new and upcoming cutting-edge instrumentation. Such instrumentation includes the LOw Frequency ARray (LOFAR) which is situated primarily in the Netherlands with additional stations currently sited across central Europe. Using data sets from various IPS-capable systems, the University of California, San Diego (UCSD) three-dimensional (3-D) tomographic-reconstruction and visualisation algorithms can yield reconstruction results for comparison with multi-point it$\$in-situ$\$ measurements from spacecraft. 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), stream interaction regions (SIRs), or their interactions with the ambient solar wind as well as the ambient wind itself. We are also testing the Faraday rotation (FR) response at low frequencies using LOFAR. Combined, these techniques have large implications and capabilities for space-weather forecasting. This work is focused on the global structure of the inner heliosphere during the minimum and rise phases of the current solar cycle.
