The passive sampling system consists of replicate CEH ALPHA® samplers attached to a shelter on a pole or post at about 1.5 m height above ground. Triplicate samplers are used in order to give a more reliable estimation of the air concentration of ammonia. \n\nAnalysis of samplers is performed by extracting exposed samplers into deionised water. This solution water is then analysed by SEAL AA3 to determine the concentration of ammonia. SEAL AA3 utilises a colourimetry response to determine concentration of ammonium. The analysis result for the concentration of ammonium on the sampler is then converted to an average concentration of ammonia in air for the specified exposure period. \n\nData processing is done by UK Centre for Ecology and Hydrology Edinburgh using the AAGA data processing tool.","metadataDate":"2026-06-29T16:22:40","notGEMINI":false,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/data/21562c80-96dc-4642-bfcf-285846000ceb","name":"Download the data","description":"Download a copy of this data","function":"download","type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/sd/21562c80-96dc-4642-bfcf-285846000ceb.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"pointsOfContact":[{"familyName":"Stephens","givenName":"Amy","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":"Stephens, A.","pointOfContact":"UK Centre for Ecology & Hydrology"}],"publicationDate":"2021-05-13T00:00:00.000Z","publishers":[{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/21562c80-96dc-4642-bfcf-285846000ceb"},{"code":"10.5285/21562c80-96dc-4642-bfcf-285846000ceb","codeSpace":"doi"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"familyName":"Stephens","givenName":"A.","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"author","email":"enquiries@ceh.ac.uk","fullName":"Stephens, A."},{"familyName":"Iwanicka","givenName":"A.","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"author","email":"enquiries@ceh.ac.uk","fullName":"Iwanicka, A."},{"familyName":"van Dijk","givenName":"N.","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"author","email":"enquiries@ceh.ac.uk","fullName":"van Dijk, N."},{"familyName":"Grimes","givenName":"R.","organisationName":"Ulster Wildlife Trust (UWT)","role":"author","email":"Roisin.Grimes@UlsterWildlife.org","fullName":"Grimes, R."},{"familyName":"Gray","givenName":"S.","organisationName":"Ulster Wildlife Trust (UWT)","role":"author","email":"Simon.Gray@UlsterWildlife.org","fullName":"Gray, S."},{"familyName":"Stephens","givenName":"Amy","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":"Stephens, A.","pointOfContact":"UK Centre for Ecology & Hydrology"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"custodian","email":"info@eidc.ac.uk"},{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"},{"organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"rightsHolder","email":"enquiries@ceh.ac.uk"}],"rightsHolders":[{"organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"rightsHolder","email":"enquiries@ceh.ac.uk"}],"spatialReferenceSystems":[{"code":"http://www.opengis.net/def/crs/EPSG/0/27700","title":"OSGB 1936 / British National Grid"}],"spatialRepresentationTypes":["textTable"],"spatialResolutions":[{"distance":"100","uom":"urn:ogc:def:uom:EPSG::9001"}],"temporalExtents":[{"begin":"2020-02-01","end":"2020-12-31"}],"title":"Monthly ammonia air concentration from Cuilcagh in Ireland/Northern Ireland, 2020","topicCategories":[{"value":"environment","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/environment"},{"value":"climatologyMeteorologyAtmosphere","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/climatologyMeteorologyAtmosphere"}],"type":"dataset","uri":"https://catalogue.ceh.ac.uk/id/21562c80-96dc-4642-bfcf-285846000ceb","useConstraints":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"}]}
