Temporal and spatial variability of Icelandic dust emissions and atmospheric transport

Popis výsledku v původním jazyce

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 (1990 to 2016) based on FLEXDUST and FLEXPART simulations and meteorological reanalysis data. Simulations for the year 2012 based on high resolution operational meteorological analyses are used for model evaluation based on PM2,5 and PM10 observations in Iceland. For stations in Reykjavik, we find that the spring period is well predicted by the model, while dust events in late fall and early winter are overpredicted. Six years of dust concentrations observed at Stórhofdi (Heimaey) show that the model predicts concentrations of the same order of magnitude as observations and timing of modelled and observed dust peaks agrees well. Average annual dust emission is 4,30 Tg during the 27 years of simulation. Fifty percent of all dust from Ic
