NASA demonstrates a model of CO2 greenhouse gas

A new video from the US Aeronautics Agency (NASA) described the process of gas causing greenhouse gases to spread throughout the world in a cycle of one year.

The video was created by GEOS-5 running on a supercomputer for more than two months, a model that recreates the chaotic interaction between atmospheric winds, weather and geographic developments , Livescience said.

The NASA team imported weather data and carbon dioxide (CO ₂ ) for decades into a specific computer model called "Nature Run" . Simulations include the amount of CO2 produced from two natural sources, such as volcanoes, and man-made, such as during the burning of fossil fuels.

Data focused on a period between May 2005 and June 2007. At that time, atmospheric CO ₂ concentrations ranged from 375 to 395 ppm. Earlier this year, CO ₂ concentrations reached more than 400 ppm for three consecutive months (that is, 400 carbon dioxide molecules in a million molecules of air).

According to simulated images, the three biggest polluters on the planet are the US, China and the European region. However, this model also emphasizes the impact of seasonal and national cycles on atmospheric CO _{2 content} .

The average concentration of CO ₂ on Earth is highest in the spring, then decreases gradually until summer, because the Northern Hemisphere plants grow and absorb CO2. Concentration of CO2 increases gradually in autumn and winter.

"It is interesting to look at each country's emissions and weather systems across the region. By combining computer simulations and live observation data, it will help improve people's understanding of CO ₂ emissions as well as natural CO2 emissions worldwide , " said Bill Putman, a project lead scientist at NASA's Goddard Space Center.
