The 2nd International Workshop of the Icelandic Aerosol and Dust Association (IceDUST) took place at the Agricultural University of Iceland in Reykjavík on February 14 2018. More than 25 scientists from 8 countries contributed by presenting current research on all aspects of volcanic dust, ash, black carbon, and other aerosol in Iceland or in global dust scale.
The workshop was a great success and it opened many research questions and future cooperation in field of Icelandic aerosol with emphasis on the effects in the Arctic and European regions. Detailed program of the Workshop can be found here:
Summary on presented topics
Olafur Arnalds was talking about ‘Aeolian rivers’ in Iceland and the importance of sediment recharging mechanisms. Mary Butwin described the impacts of eruptions on long term dust frequency showing fast removal of fresh volcanic materials. Dragana_Đorđević presented extensive data set on chemistry and mineralogy of the Rangá river sediments comparing to the Eyjafjallajökull volcanic ash. Melissa_Pfeffer summarized the measurements of Holuhraun eruption 2014-2015 showing perfect preparedness of the scientific team for future eruptions. She described all available instruments and techniques, SO2/ash ratios in measured volcanic cloud and emphasized that only the eruption of Pinatubo in 1991 has lately emitted more SO2 than Holuhraun eruption. Cameron_Powell showed the NAME volcanic ash resuspension attempts and needs to improve the forecasting. Gerður Stefánsdóttir presented long term atmospheric monitoring in Írafoss and Stórhofði and agreement of new monitoring period from 2017-2020. She emphasized the importance of long term monitoring for background conditions understanding and dramatic reductions of pH in precipitation during eruptions such as Holuhraun. Haraldur Olafsson showed the importance of locally generated winds for dust storm predictions and modelling in Iceland. Pavla Dagsson Waldhauserova summarized the underestimation of dust frequency reports from the SYNOP codes or satellite images compared to camera monitoring system of the dust hot spots. The newest research of Outi Meinander on Black and Organic Carbon presence in Icelandic snow and glaciers was presented. Konrad Kandler introduced his ideas about large field campaign that would involve neighbouring islands around Iceland. He pointed that large particles should not be omitted from the atmospheric transport studies.
Posters were on Holuhraun eruption impacts on air quality and environment by Evgenya Ilyinskaya, New COST Action InDust on dust by Sara Basart, Vertical particle profiles in Iceland by Jean Baptiste Renard, Ice-nucleation of Icelandic dust by Nsikanabasi_Umo, Turbulance measurements by LIDAR by Yang_Shu, and Dust observation in South Iceland by Lea Maria Lemarquis.
We are looking forward to meet you at the IceDust Workshop III!
