• Previous SORCE Meeting Themes
– 2002: Present Understanding of Solar Terrestrial Variations (pre-launch)
– 2003: Physical Processes Linking Solar Radiation and Solar Variability with
Global Climate Change
– 2004: Decadal Variability in the Sun and Climate
– 2005: Paleo Connections Between the Sun, Climate, and Culture
– 2006: Earth’s Radiative Energy Budget
• Next SORCE Meeting - suggestions welcomed
– Possible theme:
• Variability of the Sun and Climate during the SORCE Mission
– Solar cycle variability of the irradiance
» Physical processes on Sun causing irradiance variability
– Climate changes in atmosphere and ocean and at surface
» Physical processes of solar in fl uences on climate changes
– Possible time, location:
• late Oct - early Nov, east coast (SC ?) or Santa Fe (?)
