Agricultural ditches have been identified as emission hotspots of the three main atmospheric greenhouse gases (GHGs) i.e., carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). However, due to lack representative GHG data from these small waterbodies, their contribution total emissions agricultural sector are reported highly uncertain. In this study aim was 1) quantify magnitude understand spatiotemporal dynamics in ditches, 2) identify gas specific controls that regulate those...
Abstract This study evaluates the effect of several parameters on prediction pollutant dispersion from a stationary atmospheric source under conditions similar to those experienced by emission stacks in Alberta. Differences and similarities between Gaussian models commonly wed numerical computer are discussed. It is shown that two approaches do not correspond exactly. Both compared consistent basis. shows discretisation error model, considerable initially, but it decreases significantly for...
