1. Air quality model output for SO2 plume dispersion and deposition during 2013 AQ Oil Sands Measurement Intensive Campaign (video)
2.5 km resolution (1st time ever)
Using best and most current emissions inventory for the oils sands region developed under JOSM (CEMA/EC 2010). Outside of the OS, the emissions inventory is from 2006 for the rest of Canada. For the U.S., the inventory is for 2010 projected from the U.S inventory.
Addition of new air pollution deposition model
Improvements to dry deposition for particles
Time period for video is the time period of summer measurement intensive campaign that was done in the OS region. It ran from August 10 to September 10th, 2013.
Yellow clouds are the plumes of SO2 that are at concentrations higher than 3 parts per billion. If we showed the parts of the SO2 plumes that are less concentrated the size of the yellow clouds would be much bigger.
Rainbow colours are dry deposition of SO2. The SO2 will deposit in areas beyond the field of the clouds because SO2 is depositing from the less concentrated areas of the plume. Deposition will accumulate over the course of this 4 week video. Deposition at the end represents 4 weeks of accumulation.
