Statement

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. Measurement 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. Sample 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. Output files are in a standardised reporting template, with data quality flags (based on flags defined in ebas; https://projects.nilu.no/ccc/flags/ ). Each output file generated are time-stamped, with versioning control. An annual field calibrated ALPHA® uptake rate from the UK National Ammonia Monitoring Network project (https://uk-air.defra.gov.uk/networks/network-info?view=nh3) was applied to the ALPHA® data for the corresponding calendar year. Ratified data were generated following a multi-stage, iterative review process, with both automatic and manual data checks, in accordance with procedures in the AAGA data processing system and data review SOPs.
