Abstract In this paper impact of intensive biomass burning (BB) in North America July 2015, on aerosol optical and microphysical properties measured the European Arctic, is discussed. This study was made within framework Impact Absorbing aerosols Radiating forcing Arctic project. During BB event depth (AOD) at 500 nm exceeded 1.2 Spitsbergen 0.7 Andenes (Norway). Angstrom exponent 1.4, while absorbing varied between 1 1.25. were observed humid atmosphere with a total water vapor column 2 2.5...
During the summers of 2011 and 2012, two scientific cruises were carried out over Arctic Ocean aiming at determination aerosol chemical composition in this pristine environment. First, mass spectrometry was applied to study concentration gas/particle partitioning polycyclic aromatic hydrocarbons (PAHs) n-alkanes. Experimental modelled data phase compared: results demonstrated an equilibrium between gas particle for PAHs, while n-alkanes showed a particle-oriented partitioning, due local...
In this work multi wavelength Raman lidar data from Ny-Ålesund, Spitsbergen have been analysed for the spring 2014 Arctic haze season, as part of iAREA campaign. Typical values and probability distributions aerosol backscatter, extinction depolarisation, ratio color 4 different altitude intervals within troposphere are given. These quantities their dependencies frequency altitude-dependent observed events A comparison with ground-based size distribution chemical composition is performed....
Biomass burning related aerosol episodes are becoming a serious threat to the radiative balance of Arctic region. Since early July 2017 intense wildfires were recorded between August and September in Canada Greenland, covering an area up 4674 km2 size. This paper describes impact these biomass (BB) events measured over Svalbard, using ensemble ground-based, columnar, vertically-resolved techniques. BB influenced chemistry via nitrates oxalates, which exhibited increase their concentrations...
In this paper the authors discuss changes of aerosol optical depth (AOD) in region eastern Europe and Baltic Sea due to wild fire episodes which occurred area Belarus Ukraine 2002. The how biomass burning aerosols were advected over changed composition ensemble for a period several summer weeks. air pressure situation slow wind speeds also facilitated development such conditions. As consequence very high AOD levels recorded, by an order 3–4 higher versus normal conditions they significantly...
Light-absorbing aerosols (LAA) impact the atmosphere by heating it. Their effect in Arctic was investigated during two summer oceanographic campaigns (2018 and 2019) around Svalbard Archipelago order to unravel differences between background local anthropic settlements. Therefore, LAA rate (HR) experimentally determined. Both chemical composition high-resolution measurements highlighted substantial Ocean (average eBC concentration of 11.7 ± 0.1 ng/m3) human settlements, among which most...
This paper presents the CAMS model based aerosol optical properties calculated for two Spitsbergen fjords, Kongsfjorden (Ny-Ålesund) and Hornsund (Polish Polar Station in Hornsund) measured between 2010 2015. A small decrease Aerosol Optical Depth (AOD) is shown throughout study period leading to an alteration of state polar atmosphere. However, potential differences observed stations were not statistically significant. While during studied no significant chemical composition observed,...
Aerosol Optical Depth (AOD) is a measure of the extinction solar radiation by aerosols in atmosphere. Understanding variations global AOD necessary for precisely determining role aerosols. Arctic warming partially caused transported from vast distances, including those released during biomass burning events (BBEs). However, measuring AODs challenging, typically requiring active LIDAR systems or passive sun photometers. Both are limited to cloud-free conditions; photometers provide only point...
This paper presents the results of Aerosol Optical Depth (AOD) studies which took place in Ny-Ålesund spring 2014 during iAREA campaign. The measurements were taken using Microtops II hand-held sunphotometers along Kongsfjorden, on a path leading from research village to fjord opening. Local breeze circulation was observed measurement campaign resulted an evident increase AOD profile towards open sea. Using AOD, changes over sea have been calculated and location front has determined.
The authors provide hard evidence for a significant environmental impact of long-distance atmospheric pollution advection to the Arctic. Results from literature and their research show that inflow Arctic has been increasing over decades. biomass burning greater potential on radiative budget region than well-known spring Haze phenomenon, which always regarded as most prominent manifestation in Warming, is observed Arctic, results decreasing ice coverage region, turn, leads major changes...
Climate change and associated modification of the ocean is a fact, however, it seems to be most undervalued little understood “pandemic” challenge this century. We live in world where environmental data increasingly being amassed models are generating finer scale dense numbers outputs, resulting production high level scientific information on climate ocean. However, knowledge generated often inaccessible, incomprehensible misunderstood by society. Given that society has access many levels...
Absorbing aerosol species, such as Black (BC) and Brown (BrC) Carbon, are able to warm the atmosphere. The role of aerosols is one least clear aspects in so called “Arctic Amplification” (AA) up now this was mostly modelled [1,2]. For reason, we took part four scientific cruises (AREX, Arctic-Expedition, summer 2018, 2019, 2021 EUREC4A, 2020) North Atlantic, eastward south-eastward Barbados, aiming at determination chemical composition properties from Tropics Pole....
