The Orbiting Carbon Observatory (OCO-2) may help scientists answer key questions about how carbon cycles between Earth’s atmosphere, ocean, and land.
Atmospheric carbon dioxide concentrations reached record levels in 2013.
When Arctic permafrost thaws, it emits gases into the atmosphere that warm the climate.

NASA’s new Orbiting Carbon Observatory-2 calibrated its sensors by taking data from an area where ground stations could provide ground truth.
A holey, Swiss cheese-like landscape, thermokarst is distributed widely across the high latitudes of the northern hemisphere.
