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

Abstract

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.

Methane in West Siberia terrestrial seeps: Origin, transport, and metabolic pathways of production

“…The average annual air temperature ranges from −3°C to +1°C, while mean annual precipitation ranges from 400 to 650 mm, based on data from 1981 to 2010 (http://www.pogodaiklimat.ru, accessed on April 5th, 2022). The highest precipitation, ranging from 150 to 250 mm, occurs during the summer months (Bulatov, 2007; Dyukarev et al, 2021). The region experiences a continuous snowpack, which lasts for more than 5 months and reaches depths of 40–80 cm.…”

“…The region experiences a continuous snowpack, which lasts for more than 5 months and reaches depths of 40–80 cm. The soil in the region freezes to depths of 15–50 cm (Dyukarev et al, 2021). Snow melt typically occurs in April and May, resulting in seasonal floods that recede by the end of July.…”

“…Snow melt typically occurs in April and May, resulting in seasonal floods that recede by the end of July. The region receives more precipitation than it experiences evapotranspiration, with the average surplus being 20–100 mm (Bulatov, 2007; Dyukarev et al, 2021). The topography of the region is relatively flat, with elevations ranging from 10 to 20 m above sea level in floodplains and 30–60 m in watersheds (Bulatov, 2007; Kremenetski et al, 2003).…”

“…Wooded Hydrometeorological data are available for the MFS from 2010 to 2019 for two sites located at two distinct microtopes [41]. Data on air temperature, air humidity, atmospheric pressure, wind speed and direction, incoming and outgoing shortwave radiation, net radiation, and soil heat flux were recorded at three automated weather stations (In Situ Instruments AB, Sweden.…”
