  • Nakashima, Miye; Dagsson-Waldhauserova, Pavla (Frontiers Media SA, 2019-01-09)
    High latitude dust is an important contributor to the global dust cycle, which affects the radiative balance of the atmosphere. The frequency and severity of dust events are driven by variables such as wind speed, precipitation, temperature, surface ...
  • Kavan, Jan; Dagsson-Waldhauserova, Pavla; renard, jean-baptiste; Láska, Kamil; Ambrožová, Klára (Frontiers Media SA, 2018-12-03)
    Several important ice-free areas (e.g., Seymour Island, Cape Lamb on Vega Island, Terrapin Hill) are located in the Eastern Antarctic Peninsula region. The largest of these ice-free areas can be found on the Ulu Peninsula, James Ross Island, where this ...
  • Đorđević, Dragana; Tosic, Ivana; Sakan, Sanja; Petrović, Srđan; Đuričić-Milanković, Jelena; Finger, David C.; Dagsson-Waldhauserova, Pavla (Frontiers Media SA, 2019-07-03)
    In this work we use chemical fingerprints as characteristics ratios of specific crustal elements Ca/Al, Fe/Al, K/Al, Mg/Al, Mn/Al, Ca/Fe, and Mg/Fe to investigate the long-range transport of volcanic aerosols from Iceland. Volcanic dust enters the ...
  • Arnalds, Olafur; Dagsson-Waldhauserova, Pavla; Olafsson, Haraldur (International Society for Aeolian Research, 2016-02-15)
    Iceland has the largest area of volcaniclastic sandy desert on Earth or 22,000 km2. The sand has been mostly produced by glacio-fluvial processes, leaving behind fine-grained unstable sediments which are later re-distributed by repeated aeolian events. ...

    The Nordic Centre of Excellence CRAICC (Cryosphere–Atmosphere Interactions in a Changing Arctic Climate), funded by NordForsk in the years 2011–2016, is the largest joint Nordic research and innovation initiative to date, aiming to strengthen research ...
  • Moroni, Beatrice; Arnalds, Olafur; Dagsson-Waldhauserova, Pavla; CROCCHIANTI, Stefano; Vivani, Riccardo; Cappelletti, David (Frontiers Media SA, 2018-11-05)
    This work aims to identify the geochemical and mineralogical markers of Icelandic dust and to differentiate it from the dust of local origin deposited at the Ny-Ålesund station. We characterized representative sediment samples from Iceland and Svalbard ...
  • Möller, Rebecca; Dagsson-Waldhauserova, Pavla; Möller, Marco; Kukla, Peter; Schneider, Christoph; Gudmundsson, Magnus Tumi (Elsevier BV, 2019-11)
    In April and May 2010 the Icelandic volcano Eyjafjallajökull experienced an explosive eruption that led to substantial ashfall across the central-southern parts of the island. The resulting ash deposits covered Eyjafjallajökull, Mýrdalsjökull and parts ...
  • Olafsson, Haraldur; Arnalds, Olafur; Dagsson-Waldhauserova, Pavla; Magnúsdóttir, Agnes Ösp (MDPI AG, 2016-06-03)
    Particulate matter mass concentrations and size fractions of PM1, PM2.5, PM4, PM10, and PM15 measured in transversal horizontal profile of two dust storms in southwestern Iceland are presented. Images from a camera network were used to estimate the ...
  • Groot Zwaaftink, Christine; Arnalds, Olafur; Dagsson-Waldhauserova, Pavla; Eckhardt, Sabine; Prospero, Joseph M.; Stohl, Andreas (Copernicus GmbH, 2017-09-14)
    Icelandic dust sources are known to be highly active, yet there exist few model simulations of Icelandic dust that could be used to assess its impacts on the environment. We here present estimates of dust emission and transport in Iceland over 27 years ...
  • Urupina, Darya; Lasne, Jerome; romanias, manolis; Thiery, Vincent; Dagsson-Waldhauserova, Pavla; THEVENET, Frederic (Elsevier BV, 2019-11)
    V-dust (v-dust) is a highly variable source of natural particles in the atmosphere, and during the period of high volcanic activity it can provide a large surface for heterogeneous interactions with other atmospheric compounds. Icelandic v-dust was ...

    High Latitude Dust (HLD) contributes 5% to the global dust budget, but HLD measurements are sparse. Dust observations from Iceland provide dust aerosol distributions during the Arctic winter for the first time, profiling dust storms as well as clean ...
