5| Modeling and Network Analysis of the Oil Sands

Dr. Paul Makar

Environment and Climate Change Canada has carried out experimental high resolution forecasts (2.5km horizontal grid cell size) of the oil sands region since 2012, using the Global Environmental Multiscale – Modelling Air-quality and CHemistry (GEM-MACH) modelling system. The model has been evaluated using observations from ground monitoring stations, an aircraft monitoring intensive and satellites. Model output from these simulations have been used to estimate, for example:

- The effects of improved emissions data on model performance
- Acid deposition in Alberta and Saskatchewan
- The transport and deposition of mercury
- The effects of emissions on local weather and cloud formation

Examples from these evaluations and simulations will be presented, as well as planned future directions for the modelling work. The latter include:

- Analyses of oil sands and Alberta air-quality monitoring network observations and model output using time series and hierarchical clustering
- Simulations with observation-based emissions
- Studies of organic aerosol formation pathways
- Comparisons to aircraft-based estimates of deposition
- Further acid deposition simulations with enhanced versions of the model
- Experimental forecast simulations at 1km resolution
- Simulations to test improved methodologies for specific chemicals and groups of compounds (ammonia and PAHs, respectively).

A cascade effect is an inevitable and sometimes unforeseen chain of events due to an act affecting a system. If there is a possibility that the cascade effect will have a negative impact on the system, it is possible to analyze the effects with a consequence/impact analysis. Cascade effects are commonly visualised in tree structures, also called event trees.

Cascade effects seen in the perspective of space travelling are theoretical possibilities that space junk or a satellite destroyed by a meteor will send debris throughout the orbits of most telecommunication satellites destroying them in the process and subsequently sending that debris into all possible orbits, destroying everything in orbit around the Earth, known as the Kessler syndrome. It is theorized that if this occurs, space flight beyond Earth will become very difficult if not impossible.

In biology, according to Mold and Stein, the term cascade refers to a process that, once started, proceeds stepwise to its full, seemingly inevitable, conclusion. The main cause of a cascade of injury in medicine is by misdiagnosis and medical error. These result in iatrogenic injury and from medical error flows a cascade of effects and results often including pain, disability, loss of job, poverty and homelessness which obviously cause mental health problems and may cause death. In medicine, a cascade effect may also refer to a chain of events initiated by an unnecessary test, an unexpected result, or patient or physician anxiety, which results in ill-advised tests or treatments that may cause harm to patients as the results are pursued. An example would be ordering a full body CT scan without a clear reason, finding an incidentaloma and undergoing a debilitating surgery to remove it, despite the fact that the condition was asymptomatic and possibly benign.

There is also an ecological definition of cascade effects, in which the death of one key species in an ecosystem triggers the extinction of other species.

Thunderstorms in a Warmer World: Dr Claire Vincent (June 2017)

Claire Vincent finished her PhD in mesoscale wind variability at the Technical University of Denmark (DTU) in 2010, after which she completed a post-doc funded by the Danish Council for Independent Research, also at DTU. Prior to moving to Denmark for her PhD, Claire worked at the Australian Bureau of meteorology, first as a forecaster and then on a project to verify near-surface winds from mesoscale modelling. Claire commenced as a post-doctoral research fellow at the University of Melbourne in 2014, where she is working with analysis and modelling of tropical convection.
