| Abstract | Air pollution has become an ever more critical issue in Beijing in more recent years. In this study, we use the air quality index (AQI), corresponding primary pollutant types and meteorological data which are collected at 16 monitoring stations in Beijing between January 2013 and December, 2013 studying the spatial and temporal variations of air quality and air pollutants. The results show that $PM_{2.5}$ was the most serious pollutant, followed by $O_{3}.$ The average $PM_{2.5}$ mass concentration was $119.5 ± 13.8 μg m^{−3}$ in Beijing. In addition, the air quality varies across different seasons. More specifically, winter season showed the worst air quality. Moreover, while particulate matter $(PM_{2.5}$ and $PM_{10})$ concentrations were relatively higher in the spring and winter seasons, gaseous pollutants $(O_{3}$ and $NO_{2})$ were more serious in the summer and autumn. In terms of spatial heterogeneity, the findings showed that AQI and $PM_{2.5}$ concentrations were higher in south and lower in the north of the city, and the $O_{3}$ showed exactly a pattern with the opposite direction—higher in the north and lower in the south. $NO_{2}$ was found to have a greater impact on the central region compared with that in other regions. Furthermore, $PM_{2.5}$ was found to be positively correlated with the relative humidity, but negatively correlated with wind speed and atmospheric pressure (P < 0.01). However, the dominant meteorological factors that influence the $PM_{2.5}$ concentrations varied in different seasons. The results in this paper provide additional information for the effective control of the air pollution in Beijing. |

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.
