Interdisciplinary Global Change Research

Lead PI: Dr. Leonard M. Druyan

Unit Affiliation: Center for Climate Systems Research (CCSR)

June 2011 - September 2014
Project Type: Research

DESCRIPTION: The work relates to participation in the international project, CORDEX (Coordinated Regional climate Downscaling Experiment). CORDEX is sponsored by the World Climate Research Program of the UN and intends to produce regional climate change simulations that will contribute to the IPCC AR5. Other research includes studying climate change in the past and exploring predictions for future climate, by employing two approaches.

OUTCOMES: One uses current observations; the global temperature change is the most apparent result of climate forcing and climate change. The second approach uses Earth’s paleoclimate history. A third area of research includes research work on the ocean model HYCOM, one of two ocean circulation models that are being coupled at GISS to the atmospheric modelE for multi-century climate projections. By using a nonstandard mix of dependent and independent variables, HYCOM deviates significantly in its numerical properties from conventional Cartesian coordinate ocean models.
