Abstract
A spectrometer was used in the laboratory to study water-vapor isotope ratio measurements in air: and near . The spectral region ranging from 1483 to , which is suitable for the in situ laser sensing of major water-vapor isotopologues in the middle atmosphere from airborne or balloonborne platforms, was investigated by use of a continuous-wave distributed feedback quantum-cascade laser. The concentrations obtained were compared with the concentrations obtained with a hygrometer. The values were found to be in excellent agreement with the standard value for two individual lines. The value was slightly higher than the standard value.
