| Abstract | Surface temperature is a key factor in determining the land surface heat and water balance. Both surface temperature and soil moisture vary spatially according to soil type, land cover, and land use and temporally with the time of day and season of the year making their observation and estimation extremely difficult. The use of satellite data has become important in making temperature and soil moisture observations due to its large spatial and repeat temporal coverage. Global estimates of soil moisture require the availability of a space-based sensor. In order to achieve higher spatial and temporal resolution with spaced based sensors (passive microwave radiometers), connections must be made between the more frequently observed surface temperature and the soil moisture observations. The correlation of surface and subsurface temperature with soil moisture as well as with other meteorological data is vital for future experiments involving these parameters at regional scales using remote sensing techniques. The main focus of this paper is to analyze the change in surface temperature and soil moisture during a dry-down period, and to examine vegetation affects on surface and subsurface temperature and soil moisture. The data analyzed in this paper were collected during the Southern Great Plains 1999 Hydrology Experiment (SGP99) in Oklahoma. |

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.
