Water Isotopologue Measurements from the Yampa River Valley
https://data.eol.ucar.edu/dataset/646.001

Summary
Nearly continuous measurements of water vapor and heavy water isotopologues
taken within the Yampa Valley for the S2noCliME campaign. Measurements are
from the L-2120-i Picarro cavity ring-down spectrometer (CRDS). Data were
collected to constrain the state of the airmass within the Yampa valley and as
a complement to water isotopologue measurements taken at the summit of Storm
Peak Laboratory. The primary variables reported were water volume mixing ratio
and the ratio of the two most abundant heavy isotopologues of water (HDO and
H218O) expressed as a deviation from a standard,

Missing data exists from 1200 UTC on 12 March 2025 to 00:00 UTC on 20 March
2025 due to an instrument issue.
