NASA On Air: NASA Models CO2 Plumes - North America (11/25/2014)
LEAD: Check out this groundbreaking ultra-high-resolution computer model of carbon dioxide from NASA where one second equals one day.
1. Bright colors represent our fossil fuel and natural CO2 emissions.
2. Converging storm winds help heap up, and then disperse the CO2 through our chaotic atmosphere.
3. The concentrations build up in the heavily populated and industrial areas of the eastern U.S.
4. About one-third of CO2 emissions from the burning of fossil fuels are eventually absorbed in different land areas around the world. These are critical questions and answers needed to help understand world climate change.
TAG: This groundbreaking computer model will help scientists discover where and how CO2 is absorbed.

A Year In The Life Of Earth’s CO2
Read moreAn 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 carbon dioxide visualization was produced by a computer model called GEOS-5, created by scientists at NASA Goddard Space Flight Center’s Global Modeling and Assimilation Office.The visualization is a product of a simulation called a “Nature Run.” The Nature Run ingests real data on atmospheric conditions and the emission of greenhouse gases and both natural and man-made particulates. The model is then left to run on its own and simulate the natural behavior of the Earth’s atmosphere. This Nature Run simulates January 2006 through December 2006.While Goddard scientists worked with a “beta” version of the Nature Run internally for several years, they released this updated, improved version to the scientific community for the first time in the fall of 2014. ||
