High Latitude Dust (HLD) contributes 5% to the global dust budget and active HLD sources cover > 500,000 km2. In Iceland, desert areas cover about 44,000 km2, but the hyperactive dust hot spots of area < 1,000 km2 are the most dust productive sources. For example Hagavatn dust source of area about 10 km2 is captured on satellite images to produce visible dust plumes exceeding distance of > 700 km.
Recent studies have shown that Icelandic dust travelled about 2,000 km to Svalbard (Moroni et al., 2018) and about 3,500 km to Balkan Peninsula (Djordjevic et al., 2019). It estimated that about 7% of Icelandic dust can reach the high Arctic (N>80°). Previous study on Icelandic dust travelling about 1,300 km to Ireland (Ovadnevaite et al., 2009) serves as a case study to identify additional dust events arriving to Mace Head, Ireland in 2018-2020. In situ dust concentrations in Iceland, remote sensing and dust forecasts based on atmospheric-dust model DREAM (Dust REgional Atmospheric Model, https://sds-was.aemet.es/forecast-products/dust-forecasts/icelandic-dust-forecast) are used for this study.
