"Mesoscale meteorological models" are complex computer programs that produce predictions of meteorology, such as winds and temperature, over large areas and different heights in the atmosphere. Such information is extremely valuable in understanding the meteorological factors that influence air quality.
Reports 1 and 2 provide the results of limited investigations that were intended to test different models with the goal of improving their performance. Report 3 is an earlier effort, which assesses the different mesoscale meteorological models used to model air quality dispersion in British Columbia.
Report 1: South-Central B.C. Air Quality Ensemble Research. Jan. 1 - March 31, 2003 (Research Period.)
The Canadian Mesoscale Compressible Community Model (MC2) was run at the University of British Columbia to produce high-resolution weather forecasts
for the Okanagan and Kamloops regions. Comparisons to observed surface and upper-air soundings were made. Research was also done on developing an even higher-resolution model
called the Weather-Fire Integrated System (WFIS) coupled with MC2.

Report 2: Hind-casting of High Resolution Atmospheric Fields over Complex Terrain: Model Initialization Issues. May 2003.
The Regional Atmospheric Modelling System (RAMS) was run at the University of Northern British Columbia to produce high resolution (1 km) simulations
over the Thomson-Okanagan area using different intialization (hindcast vs. forecast) approaches. Comparisons to observed surface and upper air soundings were made.

Report 3: Using Mesoscale Modelling to Support Regulatory Dispersion Modelling. March 2002.
This report is an assessment of the different mesoscale meteorological models and provides recommendations on their application for air quality purposes.
