Hydrometeorological dataset of West Siberian boreal peatland: A 10-year record from the Mukhrino field station

Abstract

Northern peatlands represent one of the largest carbon pools in the biosphere, but the carbon they store is increasingly vulnerable to perturbations from climate and land-use change. Meteorological observations taken directly at peatland areas in Siberia are unique and rare, while peatlands are characterized by a specific local climate. This paper presents a hydrological and meteorological dataset collected at the Mukhrino peatland, Khanty-Mansi Autonomous Okrug - Yugra, Russia, over the period of 8 May 2010 to 31 December 2019. Hydrometeorological data were collected from stations located at a small pine-shrub-Sphagnum ridge and Scheuchzeria-Sphagnum hollow at ridge-hollow complexes of ombrotrophic peatland. The monitored meteorological variables include air temperature, air humidity, atmospheric pressure, wind speed and direction, incoming and reflected photosynthetically active radiation, net radiation, soil heat flux, precipitation (rain), and snow depth. A gap-filling procedure based on the Gaussian process regression model with an exponential kernel was developed to obtain continuous time series. For the record from 2010 to 2019, the average mean annual air temperature at the site was -1.0 C, with the mean monthly temperature of the warmest month (July) recorded as 17.4 C and for the coldest month (January) -21.5 C. The average net radiation was about 35.0 W m-2, and the soil heat flux was 2.4 and 1.2 W m-2 for the hollow and the ridge sites, respectively. The presented data are freely available through Zenodo ( https://doi.org/10.5281/zenodo.4323024, Dyukarev et al., 2020), last access: 15 December 2020) and can be used in coordination with other hydrological and meteorological datasets to examine the spatiotemporal effects of meteorological conditions on local hydrological responses across cold regions.
