Water Isotopes Leave Fingerprints for Climate Scientists

Date: June 25, 2013

The embedded video, produced by Marsha Walton and reported by Miles O'Brien, describes how University of Colorado meteorologist David Noone and his team are working to understand how water moves around the planet. According to the accompanying article, "The measurements are made using an optical measurement technology which has only recently become available, and which allows continuous in situ observations to be made on a practical basis. The ratio of heavier to lighter isotopes in water vapor contains information including the source region for the water vapor that falls as rain, which can be used to determine the extent to which rainwater comes directly from the ocean or from evaporation and plant transpiration over land."
