| Abstract | In September 2009, the Indian Remote Sensing OCEANSAT-2 satellite was launched from Sriharikota(India). Moreover, OCEANSAT-2 carries on-board a third payload, called ROSA (Radio Occultation Sounder of the Atmospheric) and developed by the Italian Space Agency, which give very accurate information about the vertical structure of the atmosphere, through the exploitation of the GPS Radio Occultation technique. This is a remote sensing technique aiming to characterize the Earth atmosphere. The GPS signal observed when it emerges from the Earth limb, is refracted by the Earth atmosphere; through inversion techniques, it is possible to retrieve atmospheric refractivity profiles, which in turn may be used to obtain temperature, pressure and humidity profiles. Considering that there is a great deal of data to process, this paper presents an architecture solution based on Grid Computing. We want to focus the attention on how we managed the parallelization of the processing chain of Radio Occultation data in order to evaluate the gain in performances and time obtained using the distributed architecture and for a collaborative engineering approach. |

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.
