Carbon-mapping satellite will monitor plants' faint glow

With the launch of NASA's Orbiting Carbon Observatory-2 on 1 July, scientists are not just going to get their best tool for mapping carbon sources and sinks. They are also going to get the most precise maps yet of chlorophyll fluorescence—a faint glow of light re-emitted by the plant during photosynthesis. The fluorescence—a much more direct measure for carbon uptake than proxies such as greenness or leaf area—promises to transform scientists' understanding of how ecosystems will behave under the stresses of climate change.
