The report outlines the bespoke monitoring conducted for the validation of the SCAIL tool in order to better assess that the tool provides realistic yet conservative results. Two farm sites were selected for the validation monitoring. The study collected data for odour, ammonia and airborne particulate data as well as recording on-site meteorological information. In conclusion the SCAIL-Agriculture model was found to broadly meet recognised acceptability criteria for the prediction of ammonia, PM10 and odour concentration arising from farm buildings. There are however a number of areas where further research could clearly improve the assessment of agricultural sources
