Dates: July 19-29, 2009

The next SORCE Science Meeting will be in Montreal, Canada, as part of the IAMAS Symposia, July 19-29, 2009. SORCE will participate in a special 3-day session titled “The Impact of Solar Variability on Earth” during the second week of the conference (no definite dates yet). The session will address all aspects of the impact of solar variations on the Earth’s climate, atmosphere, and oceans.

These include:

• the response to variations in total and spectral electromagnetic radiation
• the response of the atmosphere to energetic particles precipitating from the space
• the identification of mechanisms and interactions leading to indirect solar effects
• the impact of solar activity on tropospheric meteorological processes and climate

The symposium invites contributions on identifying the solar signal from ground-based and satellite observational datasets ranging from the upper atmosphere (thermosphere, mesosphere) to the troposphere, the Earth's surface and the oceans. Papers on the solar irradiance and particle flux on Earth are welcome as well as contributions on physical and chemical processes and mechanisms leading to the observed solar signal. Simulations with mechanistic, general circulation and chemistry climate models are especially encouraged. Studies may include solar variations on different time scales ranging from the 27-day rotation period over the 11-year solar cycle to centennial and millennial variations including the Maunder Minimum.

Session conveners are Ulrike Langematz (Freie Universität Berlin, Germany), Victor Fomichev (York University, Toronto, Ontario, Canada), Joanna Haigh (Imperial College, London, UK), Lon Hood (Univ. of Arizona, Tucson), Alexei Krivolustsky, Werner Schmutz (PMOD/World Radiation Center, Davos, Switzerland), and Tom Woods (LASP, Univ. of Colorado, Boulder).

As new information becomes available, it will be posted to the SORCE Science Meetings website.
