WORKING GROUP 1:
Solar Energy Flux Study: From the Interior to the Outer Layer
Coordinators: Claus Frohlich and Judit Pap
Measurements of the solar energy flux (electromagnetic radiation and the emission of charged particles) and understanding its variability are essential since they provide important information about the physical processes and structural changes taking place below, in, and above the photosphere. In addition to the astrophysical importance of the solar energy flux measurements, these measurements are important for solar- terrestrial physics. Measurements of the solar energy flux over the last decades have demonstrated that it varies with the eleven year solar activity cycle, and it has been established conclusively that the Earth's climate, radiative environment, and upper atmospheric chemistry are influenced by the varying solar energy flux. The solar variability together with the accumulation of anthropogenic trace gases determine the human milieu of the future.
The main objective of ISCS's 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. ISCS WG1 "Solar Energy Flux Study: From the Interior to the Outer Layer" has been divided into three panels:
These three panels will be concerned about measurements of the solar energy flux, analysis of the measurements, modeling the measured changes, interpreting the results and study the climate effect of solar variability. The first two panels concentrate on solar energy flux measurements, whereas the third panel concentrates on solar indices and alternative ways to model and predict irradiance variations at various wavelengths. Working Group 1 of ISCS has supported and adopted the "Thermospheric-Ionospheric Geospheric Research (TIGER)" program as part of ISCS/WG1/Panel 2. The main objectives of TIGER are to measure, model, and interpret solar EUV/UV and particle fluxes and to study and model their effect on the Earth's thermosphere and ionosphere. This approach links ISCS/WG1 activities directly with studies of our space environment.
