| Abstract | Polarized solar radiation reflected from water bodies contains useful additional information on inherent optical properties, concentrations and size distributions of water constituents if compared with unpolarized data. We report the use of a modified hyperspectral radiance sensor with very high sensitivity in order to study in detail polarization characteristics of reflectance from field measurements in coastal waters. To compare multi-angular hyperspectral field measurements with theory, radiative transfer computations of the water-leaving radiance were performed. Good agreement between simulation and angularly-resolved field measurements was observed in a certain angular range, which can be considered less affected by Sun glint. The results of the analysis are also used to develop design criteria for effective polarization sensors aimed to measure above and underwater characteristics of polarized light in coastal regions. |

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.
