International Solar Cycle Studies (ISCS), “Solar Energy Flux Study: from the interior to the outer layer” — Working Group 1 report Original Research Article

The purpose of this report is to describe the research activities and plans of Working Group 1: “Solar Energy Flux Study: From the Interior to the Outer Layer” of the International Solar Cycle Study (ISCS), which is an international research organization operating under the auspices of the Scientific Committee on Solar-Terrestrial Physics (SCOSTEP). As part of the report, we also summarize the status of the measurements and results on the solar energy flux variations. The main objective of ISCSʹs Working Group 1 is to coordinate and support comprehensive international research of the variations in the solar energy flux during the rising portion and maximum of solar cycle 23. The research activities of ISCSʹs Working Group 1 will concentrate on the following tasks: (1) to measure and study the variations in the solar radiative and mass output and solar activity indices during the solar activity cycle, (2) to understand why the solar radiative and mass output and the solar activity indices vary during the solar cycle, and (3) to study the role of solar variability in solar-terrestrial changes and its contribution to global change. ISCS WG1 “Solar Energy Flux Study: From the Interior to the Outer Layer” has been divided into three panels:
