摘要: [1] Volcanic ash forecasting is a critical tool in hazard assessment and operational volcano monitoring. The use of volcanic transport dispersion models allows analysts to determine the future location clouds. In April–May 2010, Eyjafjallajokull Iceland erupted explosively. Presented here an evaluation application weather research in-line chemistry model (WRF-Chem) applied Eyjafjallajokull. analysis focuses on first few days explosive events, April 14–19. simulations are presented along with multiple satellite ground based tools compare validate results. WRF-Chem results showed cloud dispersing toward mainland Europe, concentrations crossing Europe between 0.5–2.0 mg/m3, centered at 5 km ASL, +/−1 km. Comparisons retrievals good agreement ground-based Light Detection And Ranging (LIDAR) data compared well simulations. this manuscript has illustrated for eruptions, coupled numerical simulation important understand local atmospheric conditions as distribution. We show that fully forecast concentrations, level mg's per m3, there need accurate knowledge plume height; mass eruption rate; particle size distribution duration fusion all data. Then assessments can be performed limit impact clouds have aviation community population.
