HAVAIKI is a field experiment to make measurements of water vapor isotopologues at the NOAA observatory at Mauna Loa, Hawaii. The observations span about three weeks in October 2008, and use three different laser-based sensors and two different satellites, which will be validated against traditional mass spectrometry techniques applied to samples collected on site using vacuum flasks and cryogenic trapping. The goal of this study is to compare the different measurement techniques (traditional mass spectrometry, commercially available ground-based spectroscopic water vapor analyzers, and satellite-based spectroscopy) in order to assess the fidelity of these new measurement technologies and to provide new data on the processes that control the humidity of the subtropical Pacific.
Science objectives
- Evaluate surface-based water vapor analyzers for climate applications.
- Perform a validation of remotely sensed isotope concentrations
- Evaluate which mechanisms control mid-troposphere water vapor in the subtropics
