| Abstract | In this study, we characterized dimethylaminium (DMA ) and trimethylaminium (TMA ) in size-segregated atmospheric particles during three cruise campaigns in the marginal seas of China and one cruise campaign mainly in the northwest Pacific Ocean (NWPO). An 14-stage nano-MOUDI sampler was utilized for sampling atmospheric particles ranging from 18µm to 0.010µm. Among the four cruise campaigns, the highest concentrations of DMA and TMA in PM were observed over the South Yellow Sea (SYS) in August 2015, i.e., 0.76±0.12nmolm for DMA (average value±standard deviation) and 0.93±0.13nmolm for TMA . The lowest values were observed over the NWPO in April 2015, i.e., 0.28±0.16nmolm for DMA and 0.22±0.12nmolm for TMA . In general, size distributions of the two ions exhibited a bi-modal pattern, i.e., one mode at 0.01-0.1µm and the other at 0.1-1.8µm. The two ions' mode at 0.01-0.1µm was firstly observed. The mode was largely enhanced in samples collected over the SYS in August 2015, leading to high mole ratios of (DMA +TMA )/NH in PM (0.4±0.8, median value±standard deviation) and the ions' concentrations in PM accounting for ~10% and ~40% of their corresponding concentrations in PM . This implied that (DMA +TMA ) likely played an important role in neutralizing acidic species in the smaller particles. Using SO , NO and NH as references, we confirm that the elevated concentrations of DMA and TMA in the 0.01-0.1µm size range were probably real signals rather than sampling artifacts. |

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.
