| Abstract | Citizens are increasingly aware of the influence of environmental and meteorological conditions on the quality of their life. Thus, there has been a growing demand for personalized information about air quality and weather, i.e., information that is tailored to citizens' specific context and background. A recent poll showed that in almost all EU member states the citizens would like to have easier access to air quality related information. To address this demand, an orchestrated web service (PESCaDO) has been developed. The PESCaDO system is designed to discover reliable environmental data in the web, to process these data in order to convert them into knowledge and to use this knowledge for the provision of human-centered information. In this paper, a description of the abovementioned process is given focusing on the fusion of environmental information into a coherent data block. We will show that with the presented methods, superior temperature forecasts with respect to individual service providers can be provided to the users of PESCaDO. Furthermore, by utilizing a land use mask, a population density mask and an array of historical measurements at various locations, the regionally calibrated fusion method can be used to produce accurate air pollutant concentration maps on a local scale. In particular, we will show that the hourly average NO2 concentration in a remote city center can be predicted accurately using measurements that are no less than 50 kilometers away from the location. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
