Environmental Prediction in Canadian Cities (EPiCC) is a network of scientists seeking to better understand the atmosphere in Canadian urban environments through a program of in situ measurement, remote sensing and computational modelling.

.
Approximately 80% of Canadians reside in cities where the near-surface atmosphere is strongly affected both by the nature of the urban surface and by anthropogenic modifications to the characteristics of the urban atmosphere.

The ultimate objective of EPiCC is to provide Canadian urban residents with an improved weather and air quality forecast system through the development of an urban-atmosphere model (TEB&ISBA), evaluated in light of data collected from Canadian urban environments

By analyzing and developing these models, EPiCC aims to enhance climatic forecasting capabilities in Canadian contexts, which in turn may contribute to the safety, health and well being of Canadians.  The data EPiCC collects and the environments it models can, for example, help improve our understanding of the dispersion of smog and particulate precursors. These studies can be incorporated into procedures for anticipating heat stress, wind chill, and dispersal of air pollutants in urban environments such as accidental, industrial and terrorist releases.  EPiCC studies also provide a means of tracking efforts to conserve urban resources (e.g., energy and water utilities) and identifying the most effective ways for Canadian cities to contribute to reducing greenhouse gas emissions.

EPiCC research focuses on two Canadian cities: Montréal and Vancouver.  These cities have contrasting climates and long histories in meteorological and climatological analysis, which have produced extensive databases of urban climate research.  While EPiCC measurement operations are concentrates on these two cities, EPiCC  data and analyses have implications and applications in other contexts, such as  other urban areas throughout Canada.
