Abstract. Black carbon (BC) aerosol is considered one of the important contributors to fast climate warming and snow sea ice melting in Arctic. Yet observations BC Arctic Ocean have been limited due infrastructural logistical difficulties. We observed mass concentrations (m_BC) using light absorption methods on board icebreaker R/V Araon (166° E–156° W <80° N) as well North Pacific summer early Autumn 2016 2020. The levels, interannual variations pollution episodes m_BC were examined, emission sources responsible for high-BC analyzed with global chemistry-transport model simulations. average surface air over (72–80° 2019 was 70 ng m^–3, which substantially higher than other years (approximately 10 m^–3). much perhaps more frequent wildfires occurred region years. suggested that biomass burning composed largest contribution western marginal seas. For these five years, we identified elevated-BC episodes, including 2018 associated co-enhancements CO CH₄ but not CO₂ O₃. analysis indicated most attributed airmasses transported from boreal fires Ocean, some near-surface others mid-troposphere. This study provides crucial datasets mixing ratios O₃, CH₄, CO, regions highlights significant impact during autumn months.

Abstract. Black carbon (BC) aerosol is considered one of the most important contributors to rapid climate warming as well snow and sea ice melting in Arctic, yet observations BC aerosols Arctic Ocean have been limited due infrastructural logistical difficulties. We observed mass concentrations (mBC) using light absorption methods on board icebreaker R/V Araon (< 80° N 166° E 156° W) North Pacific summer early autumn 2016–2020. The levels, interannual variations, pollution episodes mBC were examined, emission sources responsible for high-BC analyzed with global chemistry-transport-model simulations. average surface air over (72–80° N) by 2019 cruise exceeded 70 ng m−3, which was substantially higher than that cruises other years (approximately 10 m−3). much perhaps more frequent wildfires occurring region years. model suggested biomass burning contributed western marginal seas. For these 5 years, we identified north 65° N, including 2018 associated co-enhancements CO CH4 but not CO2 O3. analysis indicated certain attributed BC-containing masses transported from boreal fire regions Ocean, some transport near others mid-troposphere.

Airborne particles in Yekaterinburg: An overview of ongoing research activities

E3S Web of Conferences, Journal Year: 2024, Volume and Issue: 575, P. 03004 - 03004

Published: Jan. 1, 2024

In the report an attempt to highlight ongoing research activities related airborne particles in Yekaterinburg has been undertaken. The attention is directed Institute of Industrial Ecology UB RAS, which atmosphere scientific program most extensive region. It consists experimental studies, represented by monitoring and sampling particulate matter, dust, sand particles, with subsequent mass spectrometric analysis; it comprises theoretical methods data processing numerical simulations spatiotemporal pollutant distribution. Because impact current studies spans beyond Ural region, seems be noteworthy exchange other groups from Central Asia around world information on where potential cooperations can established.

Application of satellite measurements for the atmospheric aerosol field assessment by the method of fluid-location of the atmosphere

27th International Symposium on Atmospheric and Ocean Optics, Atmospheric Physics, Journal Year: 2023, Volume and Issue: unknown, P. 151 - 151

Published: Oct. 17, 2023

In this work, a numerical estimate of the average field mass concentration PM_2.5 aerosol particles for European part Russia was obtained using numeric technology fluid-location atmosphere (FLA). Atmospheric concentrations reconstructed based on satellite lidar measurements were used as input information first time. According to modeling results, areas increased observed over Krasnoyarsk Krai in summer period 2021. The results compared with spatial distribution surface derived from second Modern-Era Retrospective analysis Research and Applications (MERRA-2).
