TUCSON, ARIZ. -- International scientists meeting in Tucson will report tomorrow on their research priorities for studying the sun's influence on climate.

They will conclude a 3-day workshop on the sun's role in climate change at 8:30 a.m. at the Westward Look Resort (Ocotillo Room), 245 E. Ina Road, Tucson.

The workshop is particularly timely as the peak in the current solar cycle is predicted to occur in the next few months, meeting organizers say.

The meeting is sponsored by the National Aeronautics and Space Administration (NASA) and the University of Arizona's Institute for the Study of Planet Earth (ISPE).

Participants include _

George L. Withbroe, who heads a NASA program that studies how the sun affects communications satellites and other technologies, humans in space, and Earth's environment. His focus at this meeting is on issues related to global warming and climate change.

Judith Lean of the Naval Research Laboratory and David Rind of the NASA Goddard Institute for Space Studies, who work together to distinguish the roles of the sun, greenhouse gases, and upper atmosphere ozone depletion as factors in climate change.

Jonathan T. Overpeck, who reviewed the past 1,000 years of global climate change as documented in tree rings and other proxy records, and potential evidence of their connection to solar variability.

Claus Frolich of the World (Solar) Radiation Laboratory in Davos, Switzerland. The laboratory has kept measurements made from the Earth's surface of the sun's energy over many years.

Scientists will be available for interviews tomorrow morning (March 8). Reporters are welcome to the 8:30 a.m. concluding session, said William A.. Sprigg, deputy director of ISPE and a meeting organizer.
