Stable isotopes in atmospheric water vapour from Mauna Loa, Hawaii, 2016-2017
The isotopic composition of atmospheric water vapor (1H216O, H218O, and 1H2H16O) was continuously measured at the National Oceanic and Atmospheric Administration (NOAA) Mauna Loa Observatory (MLO) from April 8, 2016 through March 13, 2017 using Off-Axis Integrated Cavity Output Spectroscopy (OA-ICOS). The dataset has been carefully corrected for humidity-dependent biases and calibrated against the international VSMOW-SLAP scale to provide a precise, continuous, nearly yearlong dataset from a dynamic subtropical setting. The measurements are provided with 15-minute and 6-hourly resolution.
This work was partially supported by NSF-AGS award 1158582 and by the University of New Mexico. This project was supported as part of a NOAA Global Monitoring Division cooperative agreement, and we thank the staff of the Mauna Loa Observatory for their assistance.
