Abstract. In this paper, spectra of aerosol optical thickness from the AERONET (AErosol RObotic NETwork) station at Hornsund in southern part Spitsbergen were employed to study impact air mass history on for wavelength λ=500 nm – AOT(500) and Ångström exponent. Backward trajectories computed, using NOAA HYSPLIT model, used trace history. It was found that spring, changes AOT values over strongly influenced by 8 days or longer duration, arriving both free troposphere an altitude 1 km above...
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....
The results of studies the vertical gradient aerosol concentration measurements made during cruises r/v 'Oceania' between 2008 and 2012 are presented. Using from those experiments, sea spray emission fluxes were calculated for all particles sizes in range 0.5 μm to 8 μm, as well fifteen channels width. information obtained was further used calculate Sea Salt Generation Function (SSGF) Baltic depending on wind speed size distribution.
The Poland-AOD aerosol research network was established in 2011 to improve aerosol–climate interaction knowledge and provide a real-time historical, comprehensive, quantitative database for the optical properties distribution over Poland. consists of institutions private owners operating 10 measurement stations an organization responsible model transport simulations. collaboration provides observations spectral depth (AOD), Ångstrom Exponent (AE), incoming shortwave (SW) longwave (LW)...
Abstract. The aim of the presented study was to investigate impact on radiation budget a biomass-burning plume, transported from Alaska High Arctic region Ny-Ålesund, Svalbard, in early July 2015. Since mean aerosol optical depth increased by factor 10 above average summer background values, this large load event is considered particularly exceptional last 25 years. In situ data with hygroscopic growth equations, as well remote sensing measurements inputs radiative transfer models, were...
A five-year dataset of spectral aerosol optical thickness was used to analyse the seasonal variability properties (the (AOT) at wavelength λ = 500 nm, AOT(500) and Ångström exponent for 440–870 nm range, α(440, 870)) over Baltic Sea dependence these on meteorological factors (wind direction, wind speed relative humidity). The data from Gotland station global radiometric network AERONET (Aerosol Robotic Network, http://aeronet.gsfc.nasa.gov) were taken be representative conditions....
Monte Carlo simulations of the expected influence nonuniformity in cloud structure and surface albedo on shortwave radiative fluxes Arctic atmosphere are presented. In particular, plane‐parallel biases transmittance studied for nonabsorbing, low‐level, all‐liquid stratus clouds over sea ice. The “absolute bias” is defined as difference between or uniform case, nonuniform conditions with same mean optical thickness albedo, averaged a given area (i.e., bias > 0 means overestimates). Ranges...
Abstract This paper addresses the influence of land topography and cover on 3D radiative effects under cloudless skies in Hornsund area, Spitsbergen, Svalbard. The authors used Monte Carlo simulations solar radiation transfer over a heterogeneous surface to study impact non-uniform on: (1) spatial distribution irradiance transmittance at fjord skies; (2) spectral shortwave aerosol forcing surface; (3) normalized nadir radiance Top Of Atmosphere (TOA) fjord. modelled transmittances radiances...
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.
This paper estimates the influence of land topography and cover on 3D radiative effects under overcast skies in Arctic coastal environment, particular Hornsund fjord region, Spitsbergen. The authors focus impact a non-uniform surface on: (1) spatial distribution solar fluxes reaching surface, (2) spectral shortwave cloud forcing at (3) flux anomaly domain resulting from assumption uniform i.e. error due to plane parallel assumptions climate models, (4) remote sensing optical thickness over...

Abstract. Black carbon (BC) is a significant forcing agent in the Arctic, but substantial uncertainty remains to quantify its climate effects due complexity of different mechanisms involved, particular related processes snowpack after deposition. In this study, we provide detailed and unique information on evolution variability BC content upper surface snow layer during spring period Svalbard (Ny-Ålesund).
