Researchers Measure Atmospheric Water Vapor Using Open-Air Spectroscopy

Researchers demonstrated that a new mid-infrared spectrometer can accurately quantify the ratios of different kinds of water—referred to as isotopologues—in atmospheric water vapor in less than 15 minutes via open air. Isotopologue ratios, which can be influenced by land-based water evaporation and plant transpiration, are used to create climate change models and to better comprehend how water moves around the world in the atmosphere.
