<description><![CDATA[The general goal of the climate research effort within SciDAC is to understand large scale climate change dynamics over very long time periods. To ensure confidence and accuracy in their simulations, climate scientists must couple many different simulation methods into a single &quot;meta-simulation&quot; that combine ocean, atmospheric, land use, vegetation, biochemistry, ecosystem dynamics, and other models. As a consequence, climate simulations often contain as many as 200 variables per grid point. Accurate simulations require a fairly short timestep - between 15 minutes and 6 hours. Performing hundreds of years of simulated time results in hundreds of terabytes of data. Since the emphasis is on large scale climate change rather than regional weather simulation, the spatial grids are generally not very large. The data-intense areas are generally multivariate and temporal. However, computational climate efforts are increasing in spatial resolution to support regional models suitable for weather forecasting. So-called &quot;ensemble runs&quot; of a given climate model produce hundreds of different simulation data sets leading to a substantial challenges in data management and comparative analysis. Such simulations are expected to provide broad insight into the impacts of human activity over long time periods, provide policy-relevant information about energy policies, and help to predict the trends of natural disasters.]]></description>

 <description><![CDATA[<a href="http://www.sci.utah.edu/gallery2/v/vacet/Climate/2009_Climate-H_264_960x540_web.mov.html"><img border="0" src="http://www.sci.utah.edu/gallery2/d/3476-16/2009_Climate-H_264_960x540_web.jpg" width="130" height="130"/></a><br/>This animated series of temperature anomaly maps was produced by averaging results from 15 of the most advanced climate models in the world.  Simulation of historical and projected climate data shows a strong warming trend in the lower atmosphere, underneath a cooling layer in the upper atmosphere.<br />
<br />
The model results shown in this video were contributed by participants in the World Climate Research Programme's Climate Model Intercomparison Project (CMIP) and were archived by the U.S. Departement of Energy's Program for Climate Model Diagnosis and Intercomparison (PCMDI) at Lawrence Livermore National Laboratory.  The data was analyzed using the Climate Data Analysis Tools developed by PCMDI.  The visualization was produced with the integrated ViSUS tools developed by VACET.]]></description>

This &quot;green CO2&quot; is the flux due to the respiration of vegetation, respiration of soil microbes, and fire minus that taken up by ecosystem production.<br />
