NASA has plans to initiate a mission to understand greenhouse gasses and vegetation. The mission would launch a satellite, the Geostationary Carbon Cycle Observatory, that will provide real time measurements of gasses.
The satellite or also known as the GeoCARB is planned to orbit 22,000 miles above the Americas where it would calculate concentrations of carbon dioxide, carbon monoxide, and methane. It would also monitor vegetation in the Americas to determine rate of growth, health, and stress.
NASA is funding the mission with $166 million over 5 years.
