The objective of this project was to transition a state-of-the-science urban flow/dispersion modeling system, developed under CRTI Project 02-0093RD, towards the status of a functional operational system prototype at Environment Canada’s Environmental Emergency Response Section (EC-EERS), a government operations centre. The proposed system will provide EC-EERS 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 flow/dispersion 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, land cover/land use classifications over Canadian cities, population distributions, CBRN source models, CBRN material and toxicological properties) to enable automated access to data required for an operat
