ecosystem on daily to seasonal time
scale
– Circulation (FY99)
– Biology (FY00)
– Atmospheric coupling (FY00)
– Collaborative Virtual Environment
– Analysis w/remote sites (FY99)
– Persistence (FY00)
– Simulation Modeling Environment
(SME) consists of modular,
pluggable components using XML

Application of Grid-based computing
allowing desktop access to remote assets
Simulation Configuration
Precipitation at Time = 6 Hrs
Runoff Amount Time = 6 Hrs
The Spatial Modeling Environment (SME)
provides an interface for desktop access to
remote supercomputing resources via a Javabased configuration manager, shown at left.
Scientists are able to remotely build, configure,
interactively run, control and visualize complex
environmental simulations. One is able to
configure simulation inputs and outputs, control
simulation dynamics and browse through the
objects of a running or paused simulation. A
palette of data viewers supports many display
formats, from the 2D desktop using VisAD
through fully immersive virtual environments
using Cave5D/Virtual Director.
