Fully Dynamic High–Resolution Model for Dispersion of Icelandic Airborne Mineral Dust

Icelandic topsoil sediments, as confirmed by numerous scientific studies, represent the largest and most important European source of mineral dust. Strong winds, connected with intensive cyclonic circulation in North Atlantic, induce intense emissions dust from local sources all year carry away these fine aerosol particles for thousands kilometers. Various impacts airborne on air quality, human health, transportation, climate marine ecosystems motivated us to design a fully dynamic coupled atmosphere–dust numerical modelling system order simulate, predict quantify process including: measurements specification over Iceland. In this study, we used Dust Regional Atmospheric Model (DREAM) improved high resolution implemented spatially variable particle size distribution, snow cover soil wetness. Three case studies short- long-range transport were selected evaluate model performance. Results demonstrated model’s capability forecast major features, such timing, horizontal vertical distribution processes. This can be an operational forecasting system, but also reliable tool assessing environmental impacts.
