| Abstract | The ocean and the atmosphere are coupled by the fluxes of momentum, heat, and water, but in situ measurements of these fluxes are sparse and uneven. Global fields of these fluxes can be derived from satellite data or obtained from operational numerical weather prediction (NWP) models. The NWP models provide quality control and dynamic interpolation of sparse and uneven data. However, dynamic interpolation is only as good as the model physics and parameterization scheme, and over most of the ocean, there may not be sufficient data for any useful interpolation. Operational NWP models change frequently; the results are inconsistent of climatic studies. Reanalysis to produce long period of consistent data have only been started recently. Adequate observations at temporal and spatial scales significant to global change research can only be achieved from the vantage point of space. Spaceborne sensors provide repeated global observations of some parameters from which these fluxes can be derived. The status and shortfalls of spacebased estimation of the fluxes are summarized and assessed in this report. Satellite data can be assimilated into numerical model to simulate surface fluxes, but the progress in developing assimilation techniques for unconventional satellite data has been slow. |

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.
