| Abstract | Passive microwave derived measures of snow water equivalent (SWE) provide an excellent means of monitoring snow cover because of a broad spatial resolution, daily orbital coverage, and all weather imaging capabilities. Combining analysis of this remotely sensed data with gridded atmospheric pressure and temperature data will allow improvement in the understanding of the complex interactions between seasonal terrestrial snow cover and overlying atmospheric systems. This study utilizes one winter season of Special Sensor Microwave/Imager (SSM/I) passive microwave SWE imagery and National Meteorological Center (NMC) gridded atmospheric data to examine an analysis methodology which utilizes both principal components analysis (PCA) and canonical correlation analysis (CCA) to link surface and atmospheric processes. The short time series was limited by data availability, but is still useful for isolating the strengths and weaknesses of the methodology, which can be applied in the future to the ever increasing time series of SWE imagery. Results show a meridional circulation pattern is linked to periods of snow accumulation, while a zonal circulation pattern corresponds to persistent snow ablation. |

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.
