| Abstract | The eruption of Icelandic volcano Eyjafjallajökull in April 2010 had a tremendous impact on global air traffic and led to 48% cancelled flights [1]. This corresponds to 10 million stranded passengers and a loss of approximately 1.5 - 2.5 billion euros for the airlines in just a few days. Within DLR's project VolcATS (Volcanic ash impact on the Air Transportation System) the eruption of Eyjafjallajökull in 2010 is reprocessed. One of the project's goals is to minimize the impact on air traffic. This contribution shows for one particular scenario the results from simulation trials with varying configurations. Optimization criteria in use are number of flights and flight duration. The target date of consideration is the $17^{th}$ April 2010 when the volcanic ash covered main parts of Europe. For simulation purpose reanalyzed ash cloud data is used. This data categorizes the ash clouds in the three zone model for low (0.2 - 2 $mg/m^{3}),$ medium (between 2 - 4 $mg/m^{3})$ and high (more than 4 $mg/m^{3})$ ash concentrations. Unlike the internationally recognized volcanic ash cloud forecasts, which are updated in a six hour interval and cover the next 24 hours with 6 hour temporal resolution, the reanalysis is updated in a three hour interval and represents actual state without forecast. To determine actual benefits from this remodeled volcanic ash data, a reference air traffic scenario from EUROCONTROL's Demand Data Repository (DDR) for the European airspace was probed against the ash clouds. On 17th April about 5 000 flights took place. On a day with normal traffic demand of 22 170 flights, the simulation shows - based on remodeled volcanic ash data - that 1 900 more flights can take place. Applying re-routing algorithms, the number of possible flights increases by another 1 500 flights. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
