| Abstract | The paper investigates atmospheric attenuation correction and ice flag algorithms for the NASA Scatterometer (NSCAT). The data from the Special Sensor Microwave/Imager (SSM/I) and SeaSat scatterometer (SASS) are analyzed to define and evaluate the applicability of potential algorithms. The results show that the monthly-averaged attenuation maps derived from the SSM/I data can be used to correct NSCAT data with a residual error of about 0.1 dB rms under rain-free conditions. However, when there is rain, the climatological attenuation map is not applicable because of the temporal and spatial variability of rain, and algorithms for rain flagging or correction remain to be investigated. NSCAT is designed to perform wind measurements over ice-free oceans. To reduce the temporal uncertainty of ice growth and motion, a sea-ice classification algorithm using the NSCAT data and the distinct physical scattering signatures of ocean surfaces and sea ice is proposed. This ice-flagging algorithm extends the performance of NSCAT into the polar oceans. |

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.
