Isotopic Composition of Central Ohio Precipitation

This resource presents δ18O, δ2H and d-excess values of central Ohio precipitation from 2012 – 2018. Samples were collected in open bucket collectors at Mansfield (40.7639°, -82.5039°), Galena (40.2151°, -82.8799°); and Columbus (40.0522°, -83.0093°). Collectors were placed in uncovered locations and sample was collected immediately after the precipitation event to minimize evaporation. Samples were analyzed on a Picarro Wavelength Scanned-Cavity Ring Down Spectroscopy Analyzer Model L1102-i or Model L2130-i. Measurement accuracy for samples was ≤3.4% and ≤4.2% for δ18O and δ2H, respectively (Leslie et al., 2014). When available, the corresponding precipitation amount, daily average air temperature, relative humidity, ground wind speed, ground wind direction are presented for samples collected in Columbus. Climate data were retrieved from the Ohio Agricultural Research and Development Center in Columbus Ohio [OARDC Weather System http://www.oardc.ohio-state.edu].
