Modelled Concentration, Deposition Fluxes and Deposition Velocities Database, Global Environmental Multiscale – Modelling Air-Quality and Chemistry Model, Oil Sands Region

This database contains surface level average concentration, average deposition velocity, and summed deposition fluxes, for the one-year period October 1, 2017 through September 30, 2018, generated using a 2.5 km resolution of the Oil Sands version of the Global Environmental Multiscale – Modelling Air-quality and CHemistry model (GEM-MACH-OS) for Alberta and Saskatchewan. These files include one-year averages of surface level concentrations, one-year averages of other model outputs such as deposition velocity, and the summed one-year totals for deposition velocity. The one-year period chosen for the extraction corresponds to the averaging time of some of the observations available for model output, which are on a bi-annual cycle. One-year totals are also a requirement for calculations of environmental impacts such as the effects of sulphur and nitrogen deposition. The mapped fields were extracted, averaged and/or summed, from 15-month hourly simulations covering the period August 1, 2017 through October 31, 2018. Files were generated for each of several simulations for the given time period - details of the model run setup, the simulations carried out, the content of each file,…
