| Abstract | Subsurface moisture and temperature, and snow/ice stores exhibit persistence on seasonal to interannual time scales. This persistence has important implications for the extended prediction of climate and hydrologic extremes. However, errors in forcing, parameterization and physics, accumulate in modeled land surface stores, which leads to future errors in water and energy partitioning. This has motivated the development of land surface data assimilation methods, which constrain land surface simulation models by forcing them primarily by observations, and by using observations of land surface storages to realistically constrain model evolution using data assimilation techniques. This development: (1) improves understanding of the time and space variability of hydrological and energy budgets, (2) mitigates land surface parameterization and observation errors through continuous simulation-observation intercomparison, and (3) improves the initialization and dynamics of land surface states in numerical weather prediction models, for more realistic weather and climate predictions. |

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.
