Image: Field testing NASA’s new carbon-dioxide measuring instrument

After years of work, a team of NASA scientists and engineers is poised to realize a lifetime goal: building an instrument powerful and accurate enough to gather around-the-clock global atmospheric carbon-dioxide (CO2) measurements from space. The instrument, called the CO2 Sounder Lidar, is a strong contender for a potential next-generation carbon-monitoring mission, the Active Sensing
