| Abstract | An analysis of the spatial and temporal variations of the polar radiation budget will undoubtedly require the use of multi-spectral satellite data. How well we can estimate the radiation balance depends on how well we can estimate the physical and microphysical properties of the surface and atmosphere that directly affect it; e.g., surface temperature and albedo, cloud particle effective radius, cloud optical depth, cloud thickness and cloud height. However, the retrieval of cloud and surface parameters is particularly problematic at high-latitudes. The authors examine their current ability to retrieve these geophysical parameters using visible and thermal satellite data, in particular the Advanced Very High Resolution Radiometer (AVHRR) on-board the NOAA polar-orbiting satellites. Both empirical and theoretical methods used in their retrieval are briefly described and the expected accuracy for each of these parameters is quantified. On the basis of their uncertainty analysis they speculate on the utility of estimating radiative fluxes derived from satellite data for the study of climate change in polar 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.
