| Abstract | A microwave model for remote sensing of snow based on dense media radiative transfer theory with random rough surface boundary conditions is developed. Both volume scattering and rough surface scattering effects are treated by numerical Maxwell model of 3D simulations (NMM3D). Detailedly, the volume scattering model is based on dense media radiative transfer (DMRT) theory by using Monte Carlo (MC) simulations of the three-dimensional solutions of Maxwell's equations for densely distributed sticky particles. The rough surface scattering is modeled by the numerical Maxwell model of 3D simulations (NMM3D), which is accelerated by sparse matrix canonical grid method (SMCG). The bistatic scattering coefficients and emissivity of rough surfaces are utilized as the boundary conditions for the DMRT. Full multiple scattering solutions are calculated by solving the DMRT numerically. The results for a layer of dry snow over a rough ground at 18.7 GHz and 38.5GHz are illustrated. |

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.
