The objective of this project was to transition a state-of-the-science urban flowdispersion modeling system, developed under CRTI Project 02-0093RD, towards the status of a functional operational system prototype at Environment Canadas Environmental Emergency Response Section EC-EERS, a government operations centre. The proposed system will provide ECEERS with the key-enabling technology to demonstrate its capability as a primary national reach-back and support centre for CBRN planning, real-time assessment, and emergency response in Canada. To achieve this objective, this project implemented three principal components 1 to provide additional advanced modeling capabilities, 2 to develop the required supporting infrastructure, and 3 to demonstrate the performance and applicability of the new operational system prototype. The first component significantly enhances the capabilities of the modeling system by incorporating thermal effects in the building-aware urban flowdispersion models improving the urban parameterization schemes used in the mesoscale flow models and developing techniques for fusion of CBRN sensor data with model predictions for source reconstruction. The second component provides all the necessary supporting databases e.g., 3D building data, landcoverland use classifications over Canadian cities, population distributions, CBRN source models, CBRN material and toxicological properties to enable automated access to data required for an operational system. The third component demonstrates and exercises the operational system for a number of CBRN scenarios in different Canadian cities, including modeling in support of events of national significance e.g., 2010 Winter Olympic Games in Vancouver, 2010 G8G20 Meetings in Toronto.
