Recent studies have called attention to the rapid growth of deposition of reduced forms of nitrogen, which would offset the benefits of reduction in oxidized nitrogen deposition. Our analysis, based on both monitoring and modeling approaches, illustrates that implementing ammonia emission abatement may not lead to full response in nitrogen deposition over continental regions. Here we provide important information to the community and policy makers concerning nitrogen deposition, given the urgent needs for developing control strategies on ammonia emissions.<\/jats:p>","DOI":"10.1073\/pnas.1920068117","type":"journal-article","created":{"date-parts":[[2020,4,20]],"date-time":"2020-04-20T20:25:29Z","timestamp":1587414329000},"page":"9771-9775","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":42,"title":["Ammonia
