EARTH MONITORING: Loss of Carbon Observatory Highlights Gaps in DataWith rising temperatures altering a variety of ecological and weather systems on Earth, the current patchwork of sensors can't answer all the questions that scientists are asking. Land-based sensors have provided a conclusive picture of rising CO2 levels worldwide, for example, but researchers don't fully understand where all the carbon that humans and natural sources are pouring into the atmosphere ends up. How much is being absorbed and where?

Watching the planet breathe
When plants photosynthesize, they use energy from sunlight to turn carbon dioxide from the air into sugars used to live and grow. In doing so, they give off a fluorescent light — a glow that can’t be seen with the naked eye, but that can be seen with the right instruments. More photosynthesis translates into more fluorescence, meaning that the plants are very productive in taking up carbon dioxide. The amount of carbon dioxide taken up by plants is called “gross primary productivity,” and is the largest part of the global carbon cycle.
