“The Impact of Solar Variability on Earth”

Download Meeting Summary (.PDF)

The 2009 SORCE Science Meeting will be held in conjunction with the IAMAS 2009 Meeting in Montreal, Canada, July 19-29.  There will be a special 2-day SORCE-related session (M03) called “The Impact of Solar Variability on Earth” on Monday-Tuesday, July 27-28.

Session M03 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).

The session will address all aspects of the impact of solar variations on the Earth’s climate, atmosphere, and oceans. These include:Montreal

  • Variability of the solar irradiance (TSI and SSI measurements and modeling)
  • Variability of energetic particle precipitation
  • Solar signal in the thermosphere, mesosphere, and stratosphere (observations, modeling, mechanisms)
  • Solar signal in the troposphere (observations and modeling, processes, climate relevance)
  • Solar signal in the oceans and the role of atmosphere-ocean coupling
  • Solar impact on centennial to millennial timescales

The symposium invited contributions (abstract deadline was Jan. 23) 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 were encouraged as well as contributions on physical and chemical processes and mechanisms leading to the observed solar signal, and especially simulations with mechanistic, general circulation and chemistry climate. Studies could 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.

The overall MOCA-09 program is now available, listing the days and times for each symposium at:  http://www.moca-09.org/e/documents/Program-framework-April1.pdf.  A detailed program listing exact days and times for each presentation will be posted on the MOCA-09 site in the coming weeks.
