SORCE
Science Working Group Meeting
The
SOlar Radiation and Climate Experiment (SORCE) Science Working
Group (SWG) Meeting was held July 17-19, 2002, in Steamboat
Springs, Colorado. Thirty-five people from around the world
participated in the two-and-one-half days of oral presentations
and poster sessions. Scientists studying the Sun and Earth's
atmosphere and climate came together to explore the variable
Sun and its influence on the terrestrial environment.
Tom Woods, the science meeting program chair, began with
a welcome and introduction to the SWG goals. By focusing
on three time domains,

the
group worked to define the present understanding of solar
and climate variations in three sessions as listed below.
Each session combined invited and contributed presentations
focusing on the solar phenomena and the climate phenomena.
The group wanted to explore the most important time periods
for variations in the Sun and Earth systems. A poster session
was held on Thursday with eleven posters.
Session
1. Short-term (minutes to 2 years) solar variations
and terrestrial variations.
Invited
Speakers - Jesper Schou (Stanford University), Jeff
Kuhn (University of Hawaii), Lon Hood (University of Arizona).
Contributed Talks - Tom Woods (LASP), Matt
DeLand (Science Systems and Applications, Inc. [SSAI]).
Session
2. Medium-term (1-30 years) solar variations
and terrestrial variations.
Invited
Speakers - Claus Fröhlich (World Radiation
Center, Switzerland), Oran White (HAO, NCAR), Robert Cahalan
(NASA, GSFC).
Contributed Talks - Rashid Akmaev (CIRES,
University of Colorado/NOAA), Matt DeLand (SSAI), Linton
Floyd (NRL/Interferometrics Inc.), Judit Pap (GSFC, University
of Maryland).
Session
3. Long-term (> 30 years) solar variations
and terrestrial variations.
Invited
Speakers - Jeffrey Hall (Lowell Observatory), Judith
Lean (NRL), David Rind (Goddard Institute of Space Studies),
Devendra Lal (Scripps Institute).
Contributed Talks - Matthew (Geoff) McHarg
(U.S. Air Force Academy). Before
beginning the sessions, Gary Rottman provided an overview
of the SORCE mission and updated everyone on the current
status. He emphasized how important this research and data
collection is for EOS science objectives. There is much
to learn about the Earth's radiation and energy balance
through continuous TSI measurements. Global energy balance
considerations may not provide the entire story, and how
TSI variations are distributed in wavelength is critically
important in understanding the Earth's response to solar
variations. He stressed that it must be a priority to continue
monitoring the total and spectral solar irradiance after
the SORCE mission is complete, and that we should now be
planning for future measurement programs. |
