This dataset is part of the International Atomic Energy Agency (IAEA) Global Network of Isotopes in Precipitation (GNIP) project and contains the total monthly precipitation quantity in millimeters collected on the roof of the National Hydrology Research Centre in Saskatoon, SK and its stable oxygen (δ18O) and hydrogen (δ2H) isotope ratios data from June 1990 to January 2020. Up until 2013, a MSC copper rain gauge, modified to hold a HDPE bottle containing a thin layer of paraffin oil to prevent evaporation collected the summer precipitation. Summer precipitation collection from 2013 onward used a Palmex integrator. A plastic 20 L bucket emptied after each snow event collected the winter precipitation until 2015 when we switched to a MSC Nipher shielded snow gauge. To determine the quantity, the collected precipitation was weigh at the beginning of each month. The precipitation’s ratios of stable oxygen (δ18O) and hydrogen (δ2H) isotopes was determined using the IAEA GNIP manual. IAEA. Statistical treatment of data on environmental isotopes in precipitation. Vienna: International Atomic Energy Agency; 1992. (Technical Series Report; 331).
