Global Modeling Initiative (GMI)

The Global Modeling Initiative (GMI) Chemical Transport Model (CTM) is part of the NASA Modeling Analysis and Prediction (MAP) program. The GMI CTM is used to assess the impacts of atmospheric circulation and composition change due to anthropogenic emissions, such as those from aircraft, biomass burning, fossil fuel combustion, and use of ozone depleting substances (ODS). GMI studies investigate changes in stratospheric ozone and the roles of long-range transport and changing emissions on air quality.

Goddard Institute for Space Studies (GISS) ModelE

The current incarnation of the GISS series of coupled atmosphere-ocean models is now available. Called ModelE, it provides the ability to simulate many different configurations of Earth System Models - including interactive atmospheric chemsitry, aerosols, carbon cycle and other tracers, as well as the standard atmosphere, ocean, sea ice and land surface components.

    NASA Center for Climate Simulation (NCCS)

    The NASA Center for Climate Simulation (NCCS) offers an integrated set of supercomputing, visualization, and data interaction technologies to enhance NASA capabilities in weather and climate prediction. It serves hundreds of users at Goddard, including the Goddard Institute for Space Studies, other NASA centers, laboratories, and universities across the U.S. The NCCS centerpiece is the “Discover” supercomputer, which hosts simulations spanning time scales from days (weather prediction) to seasons and years (short-term climate prediction) to decades and centuries (climate change projection).

    Science On a Sphere (SOS)

    This mesmerizing visualization system developed by the National Oceanic and Atmospheric Administration (NOAA) uses computers and video projectors to display animated data on the outside of a suspended, 6-foot diameter, white sphere. Four strategically placed projectors work in unison to coat the sphere with data such as '3-D surface of the earth and Nighttime Lights,' 'moon and Mars' and 'X-Ray Sun.' Maurice Henderson and system administrators, Pankaj Jaiswal and Kevin Miller, have contributed their time and expertise to the deployment of Science on a Sphere at Goddard's Visitor Center.
