Hydrometeorological, biogeochemical and stable isotope composition data from precipitations, runoff and ground ice collected near Cherskii, Russia in 2012-2015.

The data sets were compiled under the project aimed at understanding how increases in air temperature and thawing of permafrost can promote changes in magnitude and timing of streamflow in cold regions of Eurasian Arctic. Most data were collected on two small experimental watersheds near Cherskii 68°45' N 161°18' E, Yakutia, Russian Federation to quantify contributions of various water sources (rain, snow, permafrost texture ice etc) to streamflow. The data sets include hydrological and meteorological data, isotope composition data for precipitations, runoff and ground ice and some biogeochemical data from streams and ground ice over 2012-2015.
