This dataset includes daily water vapor and precipitation isotopes (δ18O and δD) and daily meteorological parameters including temperature, relative humidity, vapor concentration, air pressure, and precipitation amount at Nanjing, eastern China. Water vapor isotopes (δ18Ov and δDv) were online measured during November 2012 to December 2018 by a Wavelength Scanned Cavity Ring-Down Spectrometer (WS-CRDS, model: Picarro L2120-i) at the Station for Observing Regional Processes of the Earth System of Nanjing University (SORPES-NJU, 32.12°N, 118.95°E, 55 m above sea level) on the Xianlin Campus of the Nanjing University, about 20 km east of downtown Nanjing in the Eastern China. The uncertainties were determined to be less than 0.2‰ for δ18Ov and 1.0‰ for δDv. Precipitation isotopes were also measured by Picarro L2120-i during September 2011 to December 2018, with the analytical uncertainty of less than 0.1‰ for δ18O and 0.5‰ for δD.
