| Abstract | $MODTRAN^{reg}$ Version 5.1 includes many new capabilities tailored to enhance and facilitate atmospheric compensation. For the thermal region, the new 0.1 $cm^{-1}$ band model provides the finer spectral resolution required for analysis of state-of-the-art long-wave and mid-wave hyper- and ultraspectral imagers (e.g. AIRS). A new $MODTRAN^{reg}$ 5.1 atmospheric correction data (.acd) output file includes the specific radiative transfer quantities employed in the atmospheric compensation of solar region hyperspectral imager (e.g. MODIS, MAS) measurements; namely, DISORT-generated spectral spherical albedos and both sun-to-ground and atmospherically embedded observer-to-ground diffuse transmittances. Properly coupled observer-to-ground-to-sun path diffuse and direct transmittances are obtained when the $MODTRAN^{reg}$ correlated-k model is used to generate the .acd output. Other $MODTRAN^{reg}$ 5.1 features impacting both multi- and hyper-spectral atmospheric correction include the regeneration of molecular databases using HITRAN2004 with updates through January 2007, output of spectral channel brightness temperatures, input options facilitating perturbation of atmospheric profiles, and introduction of the $O_{2}$ - $O_{2}$ visible absorption continuum. Details of these capabilities are presented in the forward simulation mode along with applications in the reverse remote sensing mode to current satellite and aircraft sensors. |

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.
