Happy New Year?

On our way to 400ppm

NASA's Aqua spacecraft has been taking daily CO2 measurements with its Atmospheric Infrared Sounder instrument (AIRS) for the past seven years and now all that information gathering has led to beautiful and frightening maps and models of the concentration and movement of greenhouse gases in our atmosphere.
Highlighting the importance of this new data set, NASA researcher Moustafa Chahine said:

"AIRS provides the highest accuracy and yield of any global carbon dioxide data set available to the research community, now and for the immediate future," said Chahine. "It will help researchers understand how this elusive, long-lived greenhouse gas is distributed and transported, and can be used to develop better models to identify 'sinks,' regions of the Earth system that store carbon dioxide. It's important to study carbon dioxide in all levels of the troposphere."

The data reveals major findings like a belt-like ring of CO2 in the southern hemisphere where it acts as a sink for CO2 from the northern hemisphere. Also, the data shows the strong correlation between a rise in CO2 and a rise in water vapor, leading to "exacerbated" warming.
