ScienceDaily: By remotely "combing" the atmosphere with a custom laser-based instrument, researchers from the National Institute of Standards and Technology (NIST), in collaboration with researchers from the National Oceanic and Atmospheric Administration (NOAA), have developed a new technique that can accurately measure -- over a sizeable distance -- amounts of several of the major "greenhouse" gases implicated in climate change.
The technique potentially could be used in several ways to support research on...
