Airborne in situ vertical profiling of HDO / H 2 16 O in the subtropical troposphere during the MUSICA remote sensing validation campaign
Vertical profiles of water vapor (H 2 O) and its isotope ratio D / H expressed as δD(H 2 O) were measured in situ by the ISOWAT II diode-laser spectrometer during the MUlti-platform remote Sensing of Isotopologues for investigating the Cycle of Atmospheric water (MUSICA) airborne campaign. We presen...
