    dct:description "This dataset consists of monthly ammonia (NH3) measurements from ALPHA® (Adapted Low-cost Passive High Absorption) samplers co-located with UKEAP DELTA sites from January 2021 to December 2021. The UK Eutrophying and Acidifying Atmospheric Pollutants (UKEAP) network measures air pollutants at rural sites across the UK. Originally the purpose of these measurements was for validation of new PTFE membrane for ALPHA® samplers prepared at UKCEH Edinburgh research laboratory. Full details about this dataset can be found at https://doi.org/10.5285/3590613d-c462-4972-a27b-d2245e0e93a0" ;
