Abstract. The eddy-covariance technique measures carbon, water, and energy fluxes between the land surface atmosphere at hundreds of sites globally. Collections standardised homogenised flux estimates such as LaThuile, Fluxnet2015, National Ecological Observatory Network (NEON), Integrated Carbon Observation System (ICOS), AsiaFlux, AmeriFlux, Terrestrial Ecosystem Research (TERN)/OzFlux data sets are invaluable to study processes vegetation functioning ecosystem scale. Space-borne...
Abstract. Siberia is one of few continental regions in the Northern Hemisphere where atmosphere may sometimes approach pristine background conditions. We present time series aerosol and carbon monoxide (CO) measurements between September 2006 December 2011 at Zotino Tall Tower Observatory (ZOTTO) Central (61° N; 89° E). investigate seasonal, weekly diurnal variations properties (including absorption scattering coefficients derived parameters, such as equivalent black (BCe), Ångström...
Abstract. We present long-term (5-year) measurements of particulate matter with an upper diameter limit ∼ 10 µm (PM10), elemental carbon (EC), organic (OC), and water-soluble (WSOC) in aerosol filter samples collected at the Zotino Tall Tower Observatory middle-taiga subzone (Siberia). The data are complemented monoxide (CO) measurements. Air mass back trajectory analysis satellite image were used to characterise potential source regions transport pathway haze plumes. Polluted background...
Abstract. This paper analyses aerosol particle number size distributions, particulate absorption at 570 nm wavelength and carbon monoxide (CO) measured between September 2006 January 2010 heights of 50 300 m the Zotino Tall Tower Facility (ZOTTO) in Siberia (60.8° N; 89.35° E). Average number, surface volume concentrations are broadly comparable to former studies covering shorter observation periods. Fits multiple lognormal distributions yielded three maxima probability distribution...
Aerosol particle number size distributions (PNSD) were investigated to verify, if extremely low-volatility organic vapors (ELVOC) from natural sources alone could induce new formation and growth events over the remote boreal forest region of Siberia, hundreds kilometers away significant anthropogenic sources. We re-evaluated observations determined at a height 300 m observatory ZOTTO (Zotino Tall Tower Observatory, http://www.zottoproject.org). found that occurred only on 11 days in 3-year...
Boreal forests nowadays act as a sink for atmospheric carbon dioxide; however, their sequestration capacity is highly sensitive to weather conditions and, specifically ongoing climate warming. Extreme events such heavy rainfalls or, conversely, heat waves during the growing season might perturb ecosystem balance and convert them an additional CO2 source. Thus, there urgent need revise fluxes in vast Siberian taiga ecosystems influenced by extreme events. In this study, we focused on soil...
[1] The impact of wildfires on surface air composition over central Siberia is investigated based near-surface carbon monoxide (CO) measurements conducted at Zotino Tall Tower Observatory (ZOTTO), a remote station in the center Siberia, during 2007 and 2008 warm seasons. Seasonal variations intensity spatial distribution south western eastern are found to be important factors contributing substantial part synoptic year-to-year variability background CO levels region.

Fires are one of the most widespread factors changes in ecosystems boreal forests. The paper presents results a study morphological and physicochemical properties soil organic matter (SOM) Albic Podzols under pine forests (Pinus sylvestris L.) middle taiga zone Siberia (Krasnoyrsky kray) with various time passed after surface fire (from 1 to 121 years ago). influence forest fires early on chemical includes decrease acidity, content water-soluble compounds carbon nitrogen an increase light...
The present study covers more than 5 yr corresponding to 40 000 hours of particle and gas data measured at the Siberian tall tower Zotino Tall Tower (ZOTTO) (60.8°N; 89.35°E). Extrapolated along 10-d back trajectories, ZOTTO measurements cover large parts Eurasian land mass. Mapping extrapolated points major anthropogenic source regions fire regions, consistent with emission for CO vegetation fires. Middle East mid-latitude sources stand out strongly possibly emissions from Northern China...
Observations of the atmospheric sources and sinks carbon dioxide (CO2) methane (CH4) in pan-Arctic domain are extremely scarce, limiting our knowledge turnover this climatically sensitive environment fate enormous reservoirs conserved permafrost. Especially critical gaps high latitudes Siberia, covered by vast permafrost underlain tundra, where only several monitoring sites operational. This paper presents first two years (September 2018–January 2021) accurate continuous observations CO2 CH4...
Increased warming in the Arctic is of great concern. This particularly due to permafrost degradation, which expected accelerate microbial breakdown soil organic carbon, with its further release into atmosphere as carbon dioxide (CO2). The fine-scale variability CO2 fluxes across highly mosaic tundra landscapes can provide us insights diverse responses individual plant communities environmental change. In paper, we contribute filling existing gaps by investigating flux rates within different...
Boreal forest ecosystems are regions vulnerable to climate change. Such areas act as the main atmospheric carbon sinks in world. Wildfires among drivers of ecosystem modification and functioning. wildfires emit an annual average about 10% global fire emissions. Taking into account recent warming increases frequency wildfires, boreal forests might switch their functional role from sink additional source carbon. Soil respiration is second largest component cycle highly sensitive disturbance...
Atmospheric observations of sources and sinks carbon dioxide (CO2) methane (CH4) in the pan-Arctic domain are highly sporadic, limiting our understanding turnover this climatically sensitive environment fate enormous reservoirs buried permafrost. Particular gaps apply to Arctic latitudes Siberia, covered by vast tundra ecosystems underlain permafrost, where only few atmospheric sites available. The paper presents first results continuous CO2 CH4 dry mole fractions at a newly operated station...
