Monthly ammonia air concentration from Cuilcagh in Ireland/Northern Ireland, 2020
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.

Provenance & quality
The UK CEH ALPHA® sampler is a passive sampler for measuring NH3 in air. The passive sampling system consists of replicate CEH ALPHA® samplers attached to a shelter on a pole or post at about 1.5 m height above ground. Triplicate samplers are used in order to give a more reliable estimation of the air concentration of ammonia.
Analysis of samplers is performed by extracting exposed samplers into deionised water. This solution water is then analysed by SEAL AA3 to determine the concentration of ammonia. SEAL AA3 utilises a colourimetry response to determine concentration of ammonium. The analysis result for the concentration of ammonium on the sampler is then converted to an average concentration of ammonia in air for the specified exposure period.
Data processing is done by UK Centre for Ecology and Hydrology Edinburgh using the AAGA data processing tool.
