This dataset contains information ammonia concentration and deposition rates resulting from an experimental setup. An NH3 enhancement experiment was established in an ombrotrophic bog near Edinburgh, UK in 2002. Under suitable wind conditions measured, NH3 is released towards a downwind monitoring transect. Along the monitoring transect, NH3 concentrations in the air are measured using monthly passive samplers. Deposition rates are modelled using a unidirectional resistance model based on measured NH3 concentrations in the air and micrometeorology. The work was supported under the UK-SCAPE programme delivering National Capability (NE/R016429/1).

This dataset contains 90 source footprints of nitrogen and sulphur deposition across the UK. Emission data from UK sources of nitrogen and sulphur for the year 2012 has been modelled using the FRAME (Fine Resolution Atmospheric Multi-Pollutant Exchange) atmospheric dispersion model on a 5 x 5 km grid. The data are split by into both wet and dry deposition, oxidised and reduced, as well as local vs long-range components. Habitat-specific deposition data are provided also for (i) forest, (i) moorland (short semi-natural vegetation), and (iii) grid average (average of arable, grassland, urban, forest and moorland land cover types).
