Snapshots of Solar Minimum: Data and Model Results From the Past Two Solar Minima
Abstract
We present an overview of the data and models collected for the Whole Sun Month (WSM; 1996) Whole Heliosphere Interval (WHI; 2008), two international campaigns to study the three-dimensional solar-heliospheric-planetary connected system near solar minimum. The data and models from WSM, which occurred during the solar minimum between Cycles 22 and 23, provided new insight into how solar magnetic structure forms the corona and inner heliosphere. WSM inspired the Whole Heliosphere Interval campaign during the next solar minimum, and the scientific goals expanded to study how solar minimum structures affect processes in geospace. The data from WHI extended from below the solar photosphere, through interplanetary space, and down to Earth's mesosphere. Nearly 200 people participated in aspects of WHI studies, analyzing and interpreting data from nearly 100 instruments and models in order to elucidate the physics of fundamental heliophysical processes. WSM and WHI studies traced the solar activity and structure into the heliosphere and geospace, and provided new insight into the nature of the interconnected heliophysical system near solar minimum. This presentation gives insight into the motivation for the Whole Heliosphere and Planetary Interactions campaigns.
