Automated 16\u2010chamber arrays were also deployed at each site; chamber monitoring results aided the interpretation of the flux gradient results. The cumulative emissions over the six\u2010month (1 April\u201330 September) monitoring period were 2.4 \u00b1 0.7 and 2.1 \u00b1 2 kg N\n                    <jats:sub>2<\/jats:sub>\n                    O\u2010N\/ha at the no\u2010till and conventional till sites, respectively. At both sites, maximum N\n                    <jats:sub>2<\/jats:sub>\n                    O emissions occurred following the first rainfall event after N fertilization, and both sites had monthlong emission pulses.

However, these emission factors are likely conservative. We estimate that the global warming potential of the N\n                    <jats:sub>2<\/jats:sub>\n                    O emissions at these sites is larger than that of the no\u2010till conversion carbon uptake. We recommend the use of chambers to investigate spatiotemporal controls as a complementary method to micrometeorological monitoring, especially in systems with high variability. Continued monitoring coupled with the use of models is necessary to investigate how changing management and environmental conditions will affect N\n                    <jats:sub>2<\/jats:sub>\n                    O emissions.\n                  <\/jats:p>","DOI":"10.1029\/2019jg005032","type":"journal-article","created":{"date-parts":[[2019,6,22]],"date-time":"2019-06-22T07:45:29Z","timestamp":1561189529000},"page":"1887-1904","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["N\n                    <sub>2<\/sub>\n                    O Emissions From Two Agroecosystems: High Spatial Variability and Long Pulses Observed Using Static Chambers and the Flux\u2010Gradient Technique"],"prefix":"10.1029","volume":"124","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0185-1312","authenticated-orcid":false,"given":"Sarah","family":"Waldo","sequence":"first","affiliation":[{"name":"Laboratory for Atmospheric Research, Department of Civil and Environmental Engineering Washington State University  Pullman WA USA"},{"name":"National Risk Management Research Laboratory United States Environmental Protection Agency, Office of Research and Development  Cincinnati OH USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0811-5139","authenticated-orcid":false,"given":"Eric S.","family":"Russell","sequence":"additional","affiliation":[{"name":"Laboratory for Atmospheric Research, Department of Civil and Environmental Engineering Washington State University  Pullman WA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1777-6126","authenticated-orcid":false,"given":"Kirill","family":"Kostyanovsky","sequence":"additional","affiliation":[{"name":"Department of Crop and Soil Sciences Washington State University  Pullman WA USA"},{"name":"Bureau of Environmental Planning and Analysis, New York City Department of Environmental Protection  Flushing NY USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0462-1096","authenticated-orcid":false,"given":"Shelley N.","family":"Pressley","sequence":"additional","affiliation":[{"name":"Laboratory for Atmospheric Research, Department of Civil and Environmental Engineering Washington State University  Pullman WA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1555-8456","authenticated-orcid":false,"given":"Patrick T.","family":"O'Keeffe","sequence":"additional","affiliation":[{"name":"Laboratory for Atmospheric Research, Department of Civil and Environmental Engineering Washington State University  Pullman WA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David R.","family":"Huggins","sequence":"additional","affiliation":[{"name":"Northwest Sustainable Agroecosystems Research Unit, USDA\u2010ARS Washington State University  Pullman WA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudio O.","family":"St\u00f6ckle","sequence":"additional","affiliation":[{"name":"Department of Biological and Agricultural Engineering Washington State University  Pullman WA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6591-5576","authenticated-orcid":false,"given":"William L.","family":"Pan","sequence":"additional","affiliation":[{"name":"Department of Crop and Soil Sciences Washington State University  Pullman WA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7641-5227","authenticated-orcid":false,"given":"Brian K.","family":"Lamb","sequence":"additional","affiliation":[{"name":"Laboratory for Atmospheric Research, Department of Civil and Environmental Engineering Washington State University  Pullman WA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"13","published-online":{"date-parts":[[2019,7,6]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.5194\/amt-12-1095-2019"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1098\/rsta.1995.0034"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2486.2010.02260.x"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/srep15912"},{"key":"e_1_2_7_6_1","unstructured":"Bista P.
