| Abstract | Spatially distributed information about the current state of the land surface can be obtained from remote sensing measurements. These may be used with great benefit for the understanding of hydrological processes on the landscape level, where in situ measurements must fail due to lacking spatial coverage. The potential to quantify soil moisture conditions of the top soil layer, as well as the derivation of snow parameters by means of active microwave imagery has been successfully demonstrated in numerous studies. In contrast to earlier and rather experimental research efforts, data acquired from the ENVISAT ASAR sensor firstly enables to continuously monitor large areas with high temporal frequency and high spatial resolution. The different operation modes of ASAR allow the derivation of soil moisture maps on both, the field and the regional scale. The paper presents new methods to derive soil moisture and snow covered area information from ASAR wide swath (WSM) datasets. The presented approaches allocate a robust, yet practicable and reliable technique to derive near-surface soil moisture and snow patterns, being the key prerequisite for an operational application in hydrologic modelling. |

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.
