Data comprise monthly ammonia air concentrations from UK CEH ALPHA® (Adapted Low-cost Passive High Absorption) samplers co-located with UKEAP DELTA sites. The UK Eutrophying and Acidifying atmospheric Pollutants (UKEAP) network measures air pollutants at rural sites across the UK. The UK CEH ALPHA® sampler is a passive sampler for measuring NH3 in air. Originally the purpose of these measurements was for a calibrated ALPHA® uptake rate for the UK CEH Edinburgh research laboratory. Local site operator duties are completed by UK CEH staff and AFBI staff (at Hillsborough) and analysis is completed by UK Centre for Ecology and Hydrology Edinburgh. The sites were set up on 1st March 2020 and measurements are ongoing. Full details about this dataset can be found at https://doi.org/10.5285/1766eb32-1878-47e6-8dc8-d434957d1e32

This dataset consists of ammonia (NH3) measurements from a set of ALPHA (Adapted Low-cost Passive High Absorption) sampler sites in the area surrounding Cuilcagh in Ireland and Northern Ireland in 2020. The purpose of these measurements was to observe the impact of local ammonia levels on vegetation. Local site operator duties were completed by Ulster Wildlife Trust and analysis is completed by UK Centre for Ecology and Hydrology Edinburgh. The sites around Cuilcagh were started on 01.2.2020 and measurements are ongoing. Full details about this dataset can be found at https://doi.org/10.5285/21562c80-96dc-4642-bfcf-285846000ceb

This dataset contains air quality measurements: atmospheric ozone, NOx and particulate matter, for the Kirby Misperton site. British Geological Survey (BGS), the universities of Birmingham, Bristol, Liverpool, Manchester and York and partners from Public Health England (PHE) and the Department for Business, Energy and Industrial Strategy (BEIS), are conducting an independent environmental baseline monitoring programme near Kirby Misperton, North Yorkshire and Little Plumpton, Lancashire. These are areas where planning permission has been granted for hydraulic fracturing. The monitoring allows the characterisation of the environmental baseline before any hydraulic fracturing and gas exploration or production takes place in the event that planning permission is granted. The investigations are independent of any monitoring carried out by the industry or the regulators, and information collected from the programme will be made freely available to the public. ----------------------------------------------------------------------------------------------- If you use these data, please note the requirement to acknowledge use.

This data contains the emissions of ammonia (NH3) from agricultural sources in the South Asia region, for the year 2015. Agriculture is represented by five sub-sectors: crop residue burning (CRB), crop residues left in fields (CRR), livestock management (MNM), livestock grazing and manure applications (GRM), application of synthetic fertilisers (SFA). Data are bottom-up calculations using activity data and emission factors, using methods outlined in the EDGARv6.1 methodology, the IPCC 2006 Guidelines, the IPCC 2019 Guidelines Refinement and in the EMEP/EEA air pollutant emission inventory guidebooks 2019 and 2023.

This dataset contains ozone, NO, NO2, NOX, SO2 and PM2.5 air quality and meteorological measurements from two campaigns undertaken in Guangzhou, China in 2019. NO, NO2 and NOX were measured by Chemiluminescence with a Thermo scientific 42i-TL. Ozone were measured via UV with a Thermo scientific 49i. PM2.5 were measured by a continuous particulate monitor (BAM-1020, Met One instruments Inc). SO2 were measured via Pulsed fluorescence with a Thermo scientific 43i-TLE. This data were collected as part of the NERC project Investigating the large source of particulate mass from nitrophenols observed in Beijing during winter haze events (NITRO-PM).

This dataset contains total nitrogen (N) deposition at a 1km x 1km resolution in the UK, annually from 1990 to 2017. N deposition is presented as reduced N (NHx) and oxidised N (NOy), both of which are split into wet and dry portions. Values are given for forest and moorland land cover, as well as a weighted mean to each grid cell (‘grid average’).
