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).

Provenance & quality

NH3 enhancement was conducted by releasing the gas from a pure anhydrous NH3 cylinder. A mass flow controller (MFC) released pre-programmed volume of NH3 under suitable wind conditions and the release volume and time is recorded on the datalogger at 1-minute intervals. The meteorological and NH3 enhancement data was checked visually, and any obvious errors introduced by instrument malfunctioning, datalogger programming issues and power cuts were removed. NH3 concentrations were measured downwind of the source using UKCEH Adapted Low-cost Passive High Absorption (ALPHA®) samplers and analysed monthly. NH3 concentrations not following the regular exponentially declining curve with distance from the source were removed. Monthly dry deposition of NH3 to different layers of the canopy was modelled using a unidirectional resistance model written in R.
