Measurements of soil properties are also reported for each individual flux measurement.  Soil pH, temperature moisture content, bulk density and  ammonia and nitrate concentrations (extracted via the KCl method) are reported in the data. The data represents arable and grazed fields (cattle and sheep) as well as other sources of N2O from agricultural lands such as barns, manure heaps and silage storage. This data was used to assess farms scale emissions of N2O from a variety of sources over four seasons.","distributionFormats":[{"name":"Comma-separated values (CSV)","type":"text/csv","version":"unknown"}],"distributorContacts":[{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"distributor","email":"info@eidc.ac.uk"}],"id":"54edbdcf-086e-40a7-b2cc-c1e4fcbfbbbc","incomingCitationCount":0,"infoLinks":[{"url":"https://data-package.ceh.ac.uk/sd/54edbdcf-086e-40a7-b2cc-c1e4fcbfbbbc.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"inspireThemes":[{"theme":"Environmental Monitoring Facilities","uri":"http://inspire.ec.europa.eu/theme/ef"}],"keywordsOther":[{"value":"livestock farming","uri":"http://www.eionet.europa.eu/gemet/concept/4864"},{"value":"nitrogen oxides","uri":"http://www.eionet.europa.eu/gemet/concept/5613"}],"keywordsTheme":[{"value":"Agriculture","uri":"http://onto.nerc.ac.uk/CEHMD/topic/1"},{"value":"Climate and climate change","uri":"http://onto.nerc.ac.uk/CEHMD/topic/4"},{"value":"Soil","uri":"http://onto.nerc.ac.uk/CEHMD/topic/17"}],"licences":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"}],"lineage":"Flux measurements were made using a high-precision closed chamber system where air was circulated between the chamber and an Aerodyne quantum cascade laser instrument measuring mixing ratios at 1 Hz.  Fluxes were calculated from the concentration change in each chamber by linear and non-linear regression using the R package HMR which also provided the 95 % confidence interval in dc/dt.  Soil samples were collected and frozen to - 18 ˚C within six hours of collection. Analysis of soils was carried out within 2 months of sampling. NH4+ and NO3- was extracted from the soil samples using 50 ml of 1 M KCl solution for 15 g of soil.  The mixture was filtered using 2.5 µm filter paper (Fisherbrand, Hampton, New Hampshire, USA) and the solution was stored and frozen in 20 ml plastic vials. Concentrations of NH4+ and NO3- were measured using a Bran and Luebbe AutoAnalyser (SPX Flow Technology, Norderstedt, Germany) by the analytical department at the School of Geosciences, University of Edinburgh. A sub sample of the dried soils was taken to be ground (via ball milling) for elemental analysis of total carbon and nitrogen content of the soil (vario EL cube, Elemaentar, Hanau, Germany), also by the analytical department at the School of Geosciences, University of Edinburgh.","metadataDate":"2026-06-27T18:14:44","notGEMINI":false,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/data/54edbdcf-086e-40a7-b2cc-c1e4fcbfbbbc","name":"Download the data","description":"Download a copy of this data","function":"download","type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/sd/54edbdcf-086e-40a7-b2cc-c1e4fcbfbbbc.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"pointsOfContact":[{"honorificPrefix":"Dr","familyName":"Cowan","givenName":"Nicholas","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"pointOfContact","email":"enquiries@ceh.ac.uk","address":{"deliveryPoint":"Bush Estate","city":"Penicuik","administrativeArea":"Midlothian","postalCode":"EH26 0QB","country":"United Kingdom"},"fullName":"Cowan, N.","pointOfContact":"UK Centre for Ecology & Hydrology"}],"publicationDate":"2019-06-17T00:00:00.000Z","publishers":[{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"relationships":[{"relation":"http://purl.org/dc/terms/isPartOf","target":"dadbd1a5-e682-4181-a1fe-755e804a36e6"}],"resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/54edbdcf-086e-40a7-b2cc-c1e4fcbfbbbc"},{"code":"10.5285/54edbdcf-086e-40a7-b2cc-c1e4fcbfbbbc","codeSpace":"doi"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"honorificPrefix":"Dr","familyName":"Cowan","givenName":"Nicholas","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"pointOfContact","email":"enquiries@ceh.ac.uk","address":{"deliveryPoint":"Bush Estate","city":"Penicuik","administrativeArea":"Midlothian","postalCode":"EH26 0QB","country":"United Kingdom"},"fullName":"Cowan, N.","pointOfContact":"UK Centre for Ecology & Hydrology"},{"familyName":"Cowan","givenName":"N.J.","organisationName":"Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"author","email":"enquiries@ceh.ac.uk","fullName":"Cowan, N.J."},{"familyName":"Levy","givenName":"P.E.","organisationName":"Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"author","email":"enquiries@ceh.ac.uk","nameIdentifier":"https://orcid.org/0000-0002-8505-1901","fullName":"Levy, P.E."},{"familyName":"Skiba","givenName":"U.M.","organisationName":"Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"author","email":"enquiries@ceh.ac.uk","fullName":"Skiba, U.M."},{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"custodian","email":"info@eidc.ac.uk"}],"spatialReferenceSystems":[{"code":"http://www.opengis.net/def/crs/EPSG/0/27700","title":"OSGB 1936 / British National Grid"}],"spatialRepresentationTypes":["textTable"],"temporalExtents":[{"begin":"2012-09-24","end":"2013-07-10"}],"title":"Nitrous oxide fluxes and associated soil measurements from a mixed livestock farm in central Scotland (2012-2013)","topicCategories":[{"value":"farming","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/farming"},{"value":"climatologyMeteorologyAtmosphere","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/climatologyMeteorologyAtmosphere"}],"topics":["http://onto.nerc.ac.uk/CEHMD/topic/1","http://onto.nerc.ac.uk/CEHMD/topic/4","http://onto.nerc.ac.uk/CEHMD/topic/17"],"type":"dataset","uri":"https://catalogue.ceh.ac.uk/id/54edbdcf-086e-40a7-b2cc-c1e4fcbfbbbc","useConstraints":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"},{"value":"© Crown Copyright and Database Right (2019) Defra","code":"copyright"}],"version":0}
