The Final Meeting Information on “The Earth’s Radiative Energy Budget Related to SORCE” Conference Has Been Posted

The final list of invited talks at the 2006 SORCE Science Meeting, motivated by the NASA/EOS Solar Radiation and Climate Experiment (SORCE), has been posted. An earlier post on this meeting was given on April 4, 2006.

The meeting, entitled “Earth’s Radiative Energy Budget Related to SORCE” will be held in September 2006 in Washington state. Contributed papers for this meeting can be submitted until July 14, 2006.

I have reordered the list of invited speakers below to emphasize the diverse range of climate forcings, beyond the radiative effect of CO2, which will be discussed at the meeting. This meeting framework builds on the perspective provided in the 2005 National Research Council report entitled “Radiative Forcing of Climate Change: Expanding the Concept and Addressing Uncertainties”. and in the 2003 National Research Council report entitled “Understanding Climate Change Feedbacks”.

1. Aerosol Direct Effect

Brian Cairns, NASA GISS, Columbia University, New York, New York : The aerosol direct effect

2. Aerosol Indirect Effects

Jim Coakley, Oregon State University, Corvallis: The aerosol indirect effect

3. Land Use/Land Cover Change

Roni Avissar, Duke University, Durham, North Carolina: Land use/land change

4. Vegetation and other Surface Dynamics

Jay Herman, GSFC, NASA, Greenbelt, Maryland : Ozone variability and the biosphere

Al Arking, Johns Hopkins University, Baltimore, Maryland: Differential effects of SW and LW radiation on the surface energy budget and climate implications

Ellsworth Dutton, NOAA Earth System Research Laboratory, Boulder, Colorado: The surface radiative energy budgets

5. Solar forcing

Judith Lean, Naval Research Laboratory, Washington, DC: Solar radiative forcing

6. Climate feedback effects will also be presented. These include

Robert Cahalan, GSFC, NASA, Greenbelt, Maryland: Clouds and radiation

Graeme Stephens, Colorado State University, Fort Collins: The cloud-climate feedback

Judy Curry, Georgia Institute of Technology, Atlanta: Hurricane response in the climate system

Ken Jezek, Byrd Polar Research Center at Ohio State University, Columbus: The ice feedback

The presentation of the climate forcing of the well-mixed greenhouse gases will also be presented, in order to provide a perspective on the other climate forcings;

Bill Collins, National Center for Atmospheric Research (NCAR), Boulder, Colorado: Radiative forcing by greenhouse gases

Overviews of climate as a system will also be presented;

V. Ramanathan, Scripps Inst. of Oceanography, Univ. of California, San Diego : The regulation of Earth’s albedo

Ka-Kit (KK) Tung, University of Washington, Seattle: Climate responses to forcing

Peter Pilewskie, LASP, University of Colorado, Boulder: Overview of the radiation budget in the lower atmosphere

Roger Pielke Sr., University of Colorado, Boulder: Regional and global climate forcings

7. Observations of components within the Climate System

Jerry Harder, LASP, University of Colorado, Boulder: The role of VIS-IR / SIM in climate science

Greg Kopp, LASP, University of Colorado, Boulder: The role of TSI / TIM in climate science

Norm Loeb, NASA Langley Research Center, Hampton, Virginia: The accuracy of TSI / SSI in climate models

Bill McClintock, LASP, University of Colorado, Boulder: The role of UV / SOLSTICE in climate science

Xuemin Shen, Shanghai Institute of Technical Physics, China: China Earth Radiation Budget Experiment (CERBE)

Tony Slingo, University of Reading, United Kingdom: Observations of the Earth’s radiation budget from geostationary orbit and from the surface

Marty Snow, LASP, University of Colorado, Boulder: Mg II C/W index time series

Bruce Wielicki, NASA Langley Research Center, Hampton, Virginia: Earth’s radiation budget from space

Tom Woods, LASP, University of Colorado, Boulder: SORCE mission update

A major question that will be raised at this meeting is the need to better quantify the relative role of the radiative effect of CO2 on climate system heat changes (“global warming”), and the role of this climate forcing more broadly in climate variability and change. As discussed on the Climate Science weblog, the role of carbon dioxide as a fraction of the radiative heating has been overstated, based on new estimates of other radiative forcings (see). Also, the evaluation of the role of the human- and natural climate forcings and feedbacks requires a regional focus, not the use of a global average surface temperature as the climate metric to communicate to policymakers (see). The role of solar forcing will be a major topic addressed at this meeting, and the latest information on this climate forcing will be a significant contribution that results.

The September meeting (along with the Santa Fe meeting in July 2006) promise to broaden the issues in climate science that can then be communicated to other scientific colleagues and, more generally, to the public and policymakers.
