Caption: CO2 levels over North America. Computer simulation showing how carbon dioxide (CO2) travels around the globe in Earth's atmosphere, showing the results for one month (February 2006) over North America. Plumes of carbon dioxide in the simulation swirl and shift as winds disperses the greenhouse gas away from its sources. The concentration of carbon dioxide is colour-coded in parts per million by volume (ppmv) from relatively low levels (green, 380ppmv) through yellow (383ppmv) to relatively high concentrations (red, 385ppmv). The regular pulsing (green) is the daily production of CO2 by plants. High concentrations (red) can be due to natural fires and human use of fossil fuels, with high levels seen here in the USA. For similar clips, see K004/5258 (South-East Asia) and K004/5259 (Africa). This visualization is a 'Nature Run', a type of simulation that uses real data on atmospheric conditions and the emission of greenhouse gases. The simulation was produced by a computer model called GEOS-5 (Goddard Earth Observing System Model, Version 5), created at NASA Goddard Space Flight Center's Global Modeling and Assimilation Office. This is the highest-resolution simulation produced to date, with the results made available in 2014.
