At one site, ALPHA® and DELTA® methods were co-located to inter-compare NH3 concentrations. Monthly NH3 data (2019 – 2020) from the NI DELTA® network are reported separately in a companion submission.\n\nThe network is operated jointly by Agri-Food and Biosciences Institute (AFBI) and the UK Centre for Ecology & Hydrology (UKCEH), and funded by the Department of Agriculture, Environment and Rural Affairs (DAERA), Northern Ireland.","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":"7d380209-9df4-4686-b7ad-de39cca19cce","incomingCitationCount":0,"infoLinks":[{"url":"https://data-package.ceh.ac.uk/sd/7d380209-9df4-4686-b7ad-de39cca19cce.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":"NH3"},{"value":"atmospheric"},{"value":"network"},{"value":"ALPHA"},{"value":"ammonia","uri":"http://www.eionet.europa.eu/gemet/concept/375"}],"keywordsPlace":[{"value":"Northern Ireland"}],"keywordsTheme":[{"value":"Pollution","uri":"http://onto.nerc.ac.uk/CEHMD/topic/15"}],"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":"ALPHA® samplers were prepared and analysed by the UKAS accredited UKCEH Lancaster Laboratory, following protocols and procedures in manuals and Standard Operating Procedures (SOPs) developed and adopted in the UK National Ammonia Monitoring Network (NAMN), operated also by UKCEH.\n\nMeasurement frequency was monthly, with monthly site visits (± 5 days of the 1st of each calendar month) by a network of trained local site operators to exchange samples. \n\nSample exposure information (manual transcription from site recording sheets) and raw chemistry data files from analysed air samples (csv files) are stored, combined and processed in an oracle-based database (AAGA) to calculate and output calculated NH3 concentrations via a ShinyApp.\n\nOutput files are in a standardised reporting template, with data quality flags (based on flags defined in ebas;  https://projects.nilu.no/ccc/flags/).
