Objective: Investigate the spread of plume activities, its coverage area and PM 2.5 spatial impact due to forest fires
Investigation of year 2011 Forest Fires in Alberta Oil Sands Region
![Page 7: Work Term Presentation_Aaron Liu](https://reader031.vdocument.in/reader031/viewer/2022030308/58ec976d1a28ab75048b46c5/html5/thumbnails/7.jpg)
Key findings:
PM 2.5 level elevated and remained highly concentrated near CNRL Horizon monitoring station in many plume episodes, suggesting the source of emission
The PM 2.5 spatially covered a large portion of northern and central Alberta in many plume episodes
PM 2.5 level seemed very volatile due to constantly-changing meteorological factors, such as wind speed and directions
The color variation of plumes suggests PM 2.5 outward spreading direction that often aligns with wind direction

Examination of Alberta Air Mapping Tool Data Interpolation Accuracy
Objective: Determine the level of accuracy Alberta Air Mapping Tool interpolates data
Method: Purposely delete data entry in year 2015 for a particular station and use its built-in function, Time Series Data Interpolation, to estimate the missing data value via interpolation
![Page 12: Work Term Presentation_Aaron Liu](https://reader031.vdocument.in/reader031/viewer/2022030308/58ec976d1a28ab75048b46c5/html5/thumbnails/12.jpg)

Key Findings:
Among all 5 tested parameters (SO2, NO2, PM 2.5, CO, O3), SO2 appears to be the worst performing parameter with the greatest discrepancy between actual and interpolated(estimated) data due its relative low concentration.
CNRL Horizon station in year 2015SO2 vs. PM 2.5
VS.

Key Findings:
Among all tested stations in the Oil Sands region, Fort Chipewyan and Wapasu Stations seem to be the worst performing stations due to their relative isolated position and long distance to nearby stations.
VS.

Comparative analysis of different quantification approach for naphthenic acids in water
Naphthenic acids are seen as principal toxicants present in oil sands process-affected waters GC-MS/Orbitrap ≈ Total Organic Acid/Naphthenic Acid
The lower NA concentration, the less proportion it accounts within total organic acid
![Page 15: Work Term Presentation_Aaron Liu](https://reader031.vdocument.in/reader031/viewer/2022030308/58ec976d1a28ab75048b46c5/html5/thumbnails/15.jpg)
Meteorological Parameter Correlation Analysis
Key Findings:
CO and PM2.5 have substantial positive correlation
NO2 has notable negative correlation with O3 and Temperature
Data selected from Jan. 2013 to Jan. 2016Station: Fort McMurray-Athabasca Valley
![Page 16: Work Term Presentation_Aaron Liu](https://reader031.vdocument.in/reader031/viewer/2022030308/58ec976d1a28ab75048b46c5/html5/thumbnails/16.jpg)
Extension on the findings…
Since both CO and PM2.5 are usually the byproduct of combustion process, the positive correlation should come as no surprise.
The inverse relation between NO2 and O3 can be explained by:
NO+O3 → NO2 + O2
The inverse relation between NO2 and temperature is also the result of a chemical reaction:
2NO + O2 → 2NO2
The reaction is accelerated towards the right when lower temperature causes less repulsion between 2 NO molecules.

Greatly improved Excel proficiency
Better statistical & trend analysis skill
Lifetime goal: Strive to become an Excel wizard!
A slightly tweaked quote from Jim Davis:
“Excel is a powerful tool. It can tint memories of the past, shade perceptions of the present, or paint a future so vivid that it can entice... or terrify, all depending upon how we conduct it today. ”
Lesson Learned:
“An imagination is a powerful tool. It can tint memories of the past, shade perceptions of the present, or paint a future so vivid that it can
entice... or terrify, all depending upon how we conduct ourselves today. ”
