NASA’s Orbiting Carbon Observatory 2 (OCO-2; artist’s concept above), which was launched in July 2014, was designed to monitor the movement of CO2 in and out of ecosystems worldwide. Despite the satellite’s generally broad focus, its sensors are able to measure CO2 concentrations in the air to within about 1 part per million in areas covering 3 square kilometers or less. When the team combined OCO-2 data from selected... »
