    Description: Volcanic eruptions take place in Iceland about once every three to five years. Ash emissions from these eruptions can cause significant disruption to air traffic over Europe and the North Atlantic as is evident from the 2010 eruption of Eyjafjallajökull. Sulfur dioxide (SO 2 ) is also emitted by volcanoes, but there are no criteria to define when airspace is considered hazardous or non-hazardous. However, SO 2 is a well-known ground-level pollutant that can have detrimental effects on human health. We have used the United Kingdom Met Office's NAME (Numerical Atmospheric- dispersion Modelling Environment) model to simulate SO 2 mass concentrations that could occur in European and North Atlantic airspace for a range of hypothetical explosive eruptions in Iceland with a probability to occur about once every three to five years. Model performance was evaluated for the 2010 Eyjafjallajökull summit eruption against SO 2 vertical column density retrievals from the Ozone Monitoring Instrument (OMI) and in-situ measurements from the United Kingdom FAAM research aircraft. We show that at no time during the 2010 Eyjafjallajökull eruption did SO 2 mass concentrations at flight altitudes violate European air quality standards. In contrast, during a hypothetical short-duration explosive eruption similar to Hekla in 2000 (emitting 0.2 Tg of SO 2 within two hours, or an average SO 2 release rate 250 times that of Eyjafjallajökull 2010), simulated SO 2 concentrations are greater than 1063 µg/m 3 for about 48 hours in a small area of European and North Atlantic airspace. By calculating the occurrence of aircraft encounters with the volcanic plume of a short-duration eruption, we show that a 15-minute or longer exposure of aircraft and passengers to concentrations ≥500 µg/m 3 has a probability of about 0.1 %. Although exposure of humans to such concentrations may lead to irritations to the eyes, nose and throat, and cause increased airway resistance even in healthy individuals, the risk is very low. However, the fact that volcanic ash and sulfur species are not always collocated and that passenger comfort could be compromised might be incentives to provide real-time information on the presence or absence of volcanic SO 2 . Such information could aid aviation risk management during and after volcanic eruptions.

    Notes: Abstract It is shown that when a four dimensional source-free Einstein-Maxwell space-time admits a group of motions leaving the electromagnetic field unchanged a linear relation exists between two Maxwell fields and the covariant derivative of a Killing vector. For the case in which the two electromagnetic fields are related by a duality rotation it is seen that a purely geometric form of Einstein's equations may be derived. The behaviour of these under a class of quasi conformal transformations of the metric is shown to lead to Harrison's theorem.
