Minister Sherlock announces €2.1 million to detect ash clouds and improve ash dispersion and density predictions
Sean Sherlock, Minister of State for Research and Innovation today (Wednesday 19 Dec 2012) announced NUI Galway has secured funding from the European Space Agency (ESA) for a new ash cloud research project.
ESA has invested €2.1 million in an ash cloud detection and forecasting system led by the Norwegian Institute for Air Research (NILU) and involving NUI Galway and the Irish Aviation Authority Irish Aviation Authority's Volcanic Ash Detection and Forecasting Initiative. The funding was secured with the aid of Enterprise Ireland, which is the co-ordinating body for ESA in Ireland.
The project, which uses satellites and forecast models to detect ash clouds and forecast their movements, came about following the 2010 Icelandic volcano eruption, which resulted in more than 100,000 flights being cancelled, affecting 10 million passenger journeys during the first week of the eruption alone.
Announcing the investment, Minister Sherlock said; "The Action Plan for Jobs 2012 puts innovation and technology at the heart of enterprise and jobs policies and working with the European Space Agency is an integral part of driving innovation and research in Ireland."
"NUI Galway's commitment to developing new environmental monitoring techniques is impressive. This is a significant win for NUI Galway and clearly indicates that Irish Research Institutes have the capability and expertise to significantly contribute to these pan European projects."
The Minister added 'Ireland's membership of the European Space Agency is having a direct and positive impact for the research and SME community. There are over 40 Irish companies that are active in ESA programmes. These companies, through their involvement with ESA Earth observation programmes, are also directly impacting on global threats such as climate change, ozone depletion, maritime surveillance, flooding and forest fires'.
In addition to ash detection via satellite platforms, the Irish Aviation Authority (IAA), in collaboration with NUI Galway, is deploying an ash cloud detection network composed of four ground-based LIDARS (dust or haze RADARs) located strategically at north, south, east and west perimeters in Ireland. ESA have invested in NUI Galway's School of Physics and Centre for Climate & Air Pollution studies to use the LIDAR data for ash detection.
In total, ESA have invested €2.1 million in the Volcanic Ash Strategic-initiative Team (VAST). VAST is a consortium led by NILU and comprises teams from Finland, Austria and Ireland with NUI Galway being awarded €500,000 to further develop and evaluate their ash forecast model, to develop real-time ash detection software and techniques for the LIDAR network, and to conduct the validation of the detection and forecasting aspects of the project.
Professor Colin O'Dowd, the Director of the Centre for Climate & Air Pollution Studies, based in the Ryan Institute at NUI Galway, said: "The VAST detection and forecasting system is especially designed to facilitate the aviation industry and represents a major technological step forward in combing space-borne and ground-based remote-sensing platforms with sophisticated ash forecasting models and will put Europe in poll position in terms of ash cloud detection and forecasting."
He went on to say "ESA's investment in NUI Galway's research and research support staff for the IAA's LIDAR network is a reflection of how important ESA views the Irish contribution to ash cloud detection and prediction. The initiative will provide more accurate information to the aviation industry which is expected to result in reduced disruption of air travel as 'fly' or 'no-fly' decisions will be based on more accurate predictions of ash plume location and density."
Dr. Barry Fennell of Enterprise Ireland and National Delegate to ESA's Earth Observation Programme Board said "Ireland's unique geographical position on the western fringes of Europe makes it an ideal and much sought after international partner when developing early detection environmental warning systems whether focused on the atmosphere, on land or on the marine environment. Many more business opportunities for Irish Industry will become available over the coming years through increased availability and access to data collected in-situ and from Earth Observation satellites."
"Ireland's recent renewal of its membership to the ESA Earth Observation programme with a subscription of €5 million will secure the position of our SME's, Academic and Public Sector institutes at the heart of the latest technological developments in this rapid advancing area of service development."

Notes for the Editor
In 2010, the Icelandic volcano, Eyjafjallajökull, erupted explosively, ejecting an ash plume 4-9 km into the atmosphere. Although regarded as a moderate and mid-sized eruption, it had a severe impact on aviation over Europe. Following recommendations from the European Volcanic Ash Advisory Centres (VACCs), the European aviation authorities decided to close European air space, impacting air traffic to 23 European countries amounting to a 75% closure of the European aerodrome network. The net effect was that more than 100,000 ﬂights were cancelled, aﬀecting 10 million passenger journeys during the first week of the eruption.
Decisions on fly or no-fly centred around estimates of the ash mass density exceeding approximately 2 mg m-3, although in practice no robust measurements of the plume mass density were achieved and most estimates of the plume density derived from the VACC's dispersion models, with a high degree of uncertainty.
The unexpected eruption and impact revealed several deficits in Europe's capabilities in terms of accurately detecting and predicting the volcanic ash plume density, thickness and vertical extent. Following the joint ESA and EUMETSAT workshop to evaluate the impact of the eruption and how to respond to future eruptions (hosted by ESA ESRIN, Frascati, May 2010, scientists have studied the Icelandic ash plumes extensively and have invested considerable effort into scoping out and designing the best detection and warning system to put in place.
