A field study examining CO₂ and total hydrocarbon (THC) emissions was performed at a refinery landfarm in southwestern Ontario during the fall of 1999. The geometry of the landfarm was such that there was limited fetch in some wind directions. To maximize the amount of flux data collected, both flux gradient and aerodynamic mass balance micrometeorological approaches were used to estimate trace gas fluxes during active landfarm operations. Through examination of the resultant fluxes and the use of an analytical footprint model, an analysis of fetch requirements will be presented. This can be used to illustrate the strengths and weaknesses of the two micrometeorological methods for sites with limited fetch. Using two different micrometeorological methods maximized data collection for the site geometry and minimal data was discarded due to poor wind directions.
