英文摘要 | Metrics for the risk associated with the threat that airborne volcanic ash particles pose to commercial jet aircraft are presented using simulations based on a Lagrangian particle transport and dispersion model driven by satellite measurements for the Eyjafjallajokull volcanic eruption, Iceland, for the period 14 April to 23 May 2010. The study utilizes a four-dimensional data set of simulated ash concentrations together with European and trans-Atlantic air routes to determine metrics corresponding to the total mass intercepted (defined as the dose), the mass interception rate (the dose rate), and the concentration (the exposure) over time (the dosage) that a jet aircraft encounters along the air route. The methodology can be used as a logistical and flight planning tool in a forecast mode and also in hindcast mode to assess the extent of airline fleet exposure to ash following an eruption, thereby providing operators with information useful for flight safety. Plain Language Summary Volcanic ash that is dispersing in the atmosphere is a hazard to jet aircraft. We suggest new metrics for quantifying volcanic ash as a hazard to aviation by using a three-dimensional model/satellite data set derived for the 14 April to 23 May 2010 eruption of Eyjafjallajokull, Iceland. The metrics include dose rate, dose, dosage, and exposure. These are calculated for fictitious flight routes across Europe and for some trans-Atlantic routes. The methodology is globally applicable and may be of use to airlines, regulators, and other aviation stakeholders. |
