The Joint Global Change Research Institute (JGCRI) is the home and primary development institution for GCAM, an open source model that represents the linkages between energy, water, land, climate, and economic systems. GCAM is a market equilibrium model, is global in scope, and operates from 1990 to...

Increasing levels of nutrients, persistent hypoxia, harmful algal blooms, and increased frequency of fish kills are degrading the ecological health of the Salish Sea. An improved version of a diagnostic hydrodynamic and biogeochemical model (nutrients, phytoplankton, carbon, dissolved oxygen, and pH...

The VAST Contest is a participation category of the IEEE VAST Annual Symposium. It continues in the footsteps of the VAST 2006 contest as its purpose is to promote the development of benchmark data sets and metrics for visual analytics, and to establish a forum to advance visual analytics evaluation...
