Stable isotope data of daily precipitation during the period of 2013-2017 from K-puszta (regional background monitoring station), Hungary

Precipitation was collected on daily basis at K-puszta regional background monitoring station located near Kecskemet, in the western part of the Great Hungarian Plain, between 1 April 2013 and 31 December 2017 for stable hydrogen and oxygen analyses. The sample collection period covered 24 hours, from 07:00 to 07:00 h LT (Local Time) the next day. Stable hydrogen and oxygen isotope composition of the daily precipitation samples were measured using a Liquid Water Isotope Analyser (LWIA-24d) manufactured by Los Gatos Research Ltd. The dataset includes 472 stable isotopic data representing the continuation of the beforehand monitoring started in 2012 [1]. The dataset provides a unique opportunity to combine daily meteorological data and stable isotope composition of daily precipitation which can help to improve our understanding of the processes and factors at relatively high resolution that govern delta D and delta O-18 values of the precipitation. In addition, the dataset can be used as an isotope hydrological benchmark in comparison with sta-ble isotope dataset obtained from surface-and groundwater or other sources (e.g. climate proxies, agricultural products). Thus, research related to isotope hydrology, agriculture, pale-oclimate can benefit from this dataset. Interpretation of this dataset focusing on the relationship between meteorological factors and stable isotope composition of precipitation is in progress. (C) 2021 The Authors.
