| Abstract | SO2 is one of the main atmospheric pollution components, and usually used as an indicator to monitor the environmental pollution. The spatio-temporal of SO2 in urban aera provides critical information on the air quality controlling. Being the developed district of China, Zhejiang Province is a typical region suffered from air pollutions as results of human activities. In this paper, OMI SO2 column remotely sensed data from 2005.1 to 2008.12 and the land use mapping using MODIS-EVI data, as well as to combine with SO2 ground measured data are get together, and serve for analyzing the relationship between SO2 column density and the regional land use change of Zhejiang Province. The results showed that there was a significant correlation between SO2 column density and the SO2 ground observation data $(R^{2}$ = 0.793). SO2 column density had obviously reduced from 2005 to 2008 in the Zhejiang Province of China. The highest SO2 column density usually appeared at northen area of Zhejiang Province in winter. The SO2 column density was declined along with the gradient from northern to southern area as the economic development and urbanization. We found there were significant negative relationships between land use and SO2 column density. The highest SO2 column density appeared at northern urban area, which is much higher than the others. The SO2 column density was the lowest in forest region. The results approved that the OMI SO2 column remotely sensed data can be used in air quality monitoring at regional scale. |

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.
