| Abstract | Soils are among the major sources of atmospheric nitric oxide (NO), which play a crucialrole in atmospheric chemistry. Here we systematically synthesized the modeling studies andfield measurements and presented a novel soil NO emission inventory of terrestrialecosystems in China. The previously modeled inventories ranged from 480 to 1375 and from242.8 to 550 Gg N yr−1 for all lands and croplands, respectively.Nevertheless, all the previous modeling studies were conducted based on very fewmeasurements from China. According to the current synthesis of field measurements, most soilNO emission measurements were conducted at croplands, while the measurements were onlyconducted at two sites for forest and grassland. The median NO flux was 3.2 ng Nm−2 s−1 with a fertilizer induced emission factor (FIE) of0.04% for rice fields, and was 7.1 ng N m−2 s−1 with an FIE of0.67% for uplands. A novel NO emission inventory of 1226.33 (ranging from 588.24 to 2132.05)Gg N yr−1 was estimated for China's terrestrial ecosystems, which was about18% of anthropogenic emissions. More field measurements should be conducted to cover morebiomes and obtain more representative data in order to well constrain soil NO emissioninventory of China. |

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.
