Please join us for a four-day workshop focused on observational and modeling studies of the influences of solar radiation and energetic particle precipitation (EPP) on the atmosphere and climate. The meeting will last four full days, beginning Tuesday morning, 9 October. Broad topics to be covered include the causes and phenomenology of solar radiation and energetic particle variability, mechanisms by which radiative and particle forcing affect atmospheric chemistry and dynamics, contributions of solar and EPP forcing to climate variability and space weather, and the current state of the art and outlook for relevant observations and models. (Agenda)

Format: Because of the interdisciplinary nature of this workshop, there will be several plenary sessions during which invited tutorials and overview talks will be geared toward the general audience. All contributed presentations will be given in the form of posters, for which individual, sequential sessions will be scheduled. All contributors will be given the opportunity to present a one-slide summary of their posters in the oral plenary sessions. Lively discussions will be encouraged, with abundant time for collegial interactions during poster sessions. The last day of the meeting will be reserved for the HEPPA and SOLARIS model/measurement inter-comparison working groups, which are open to all interested participants.

Invited talks will be given by: Bernd Funke, Larisa Goncharenko, Richard Horne, Kuni Kodera, Jon-Egill Kristjansson, Charles Jackman, Harry van Loon, Daniel Marsh, Katja Matthes, Jerry Meehl, Peter Pilewskie, Craig Rodger, Annika Seppälä, Nathan Schwadron.
