A NEW WAY TO SEE CLIMATE CHANGE

NASA Computer Model Provides a New Portrait of Carbon Dioxide

Patrick Lynch, November 17, 2014 (NASA)

“An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe…Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources. The simulation also illustrates differences in carbon dioxide levels in the northern and southern hemispheres and distinct swings in global carbon dioxide concentrations as the growth cycle of plants and trees changes with the seasons…[The simulation uses ground-based measurements of carbon dioxide and measurements from the Orbiting Carbon Observatory-2 (OCO-2) satellite. It is] the product of a new computer model [called GEOS-5] that is among the highest-resolution ever created…[and] is the first to show in such fine detail how carbon dioxide actually moves through the atmosphere…[It] is part of a simulation called a [Nature Run that] ingests real data on atmospheric conditions and the emission of greenhouse gases and both natural and man-made particulates…[and runs on its own to simulate] the natural behavior of the Earth’s atmosphere. This Nature Run simulates May 2005 to June 2007…” click here for more
