Water Vapor Isotopic Composition During SAIL

Overview:

Measurements of the stable isotopic composition of water vapor were collected between 21 November 2022 and 1 June 2023 at the SAIL campaign main site in Gothic Colorado.  The data were obtained using a Los Gatos Research Triple Water Vapor Isotopic Analyzer from a heated and insulated inlet mounted on the roof of the guest instrument van.  Standards were run periodically during the campaign and the data were corrected for humidity-dependent biases and were normalized to the VSMOW/SLAP scale.  Uncertainties in dD and d18O are estimated to be 2.28 permil and 0.38 permil, respectively.

Abstract:

Measurements of the stable isotopic composition of water vapor were collected between 21 November 2022 and 1 June 2023 at the SAIL campaign main site in Gothic Colorado.  The data were obtained using a Los Gatos Research Triple Water Vapor Isotopic Analyzer from a heated and insulated inlet mounted on the roof of the guest instrument van.  Standards were run periodically during the campaign and the data were corrected for humidity-dependent biases and were normalized to the VSMOW/SLAP scale.  Uncertainties in dD and d18O are estimated to be 2.28 permil and 0.38 permil, respectively.
Purpose:

The isotopic data from SAIL should provide constraints on the local hydrologic cycle, including regional water vapor transport processes and sublimation/evaporation processes.
Data Usage:The data may be merged with complementary datasets such as routine meteorology, aerosol, or radar data for studies of the water cycle.
