The EPiCC network is a multi-year (2006-2010) project of university and government researchers intended to provide a version of the TEB-ISBA (TEB - Town Energy Balance; ISBA - Interactions Soil-Biosphere-Atmosphere) model (Masson 2000, Noilhan and Planton 1989) optimized and verified for conditions found in Canadian cities and ready for operational implementation in the Canadian Meteorological Centre numerical prediction system. The modeling component includes mesoscale atmospheric modeling and studies of the atmospheric boundary layer as well as development and evaluation of the TEB-ISBA system. The model system will be evaluated for the winter response of anthropogenic heat forcing (Montréal) and the summer response of anthropogenic water forcing (through garden irrigation in Vancouver). Development of the TEB hydrological parameterization and advective feedback in the TEB-ISBA coupling are planned. The observational component is comprised of long term continuous observations of the radiation and energy balance including CO 2 concentrations and fluxes in Montréal and Vancouver with seasonal deployment of other instrumentation. Rural baseline observations are also included. The remote sensing component includes evaluation and continued development of an urban land use characterization scheme that provides the surface information necessary for the TEB-ISBA modeling system, use of airborne LiDAR data to help parameterize the vertical and horizontal structure of urban environments for the modeling system (including both the built and vegetated environment) and use of other ground or space-based remote sensing to assess surface characteristics, especially temperature and snow cover.

EPiCC is proposing to hold IOPs for select periods inMontreal and Vancouver. These IOPs will provide the
opportunity to make use of the EPiCC network
infrastructure and undertake detailed studies of the urbanatmosphere that will contribute to network objectives.
Anticipated dates: summer-time IOP for Vancouver and
both summer and winter IOPs for Montreal during theperiod Winter 2008 – Fall 2009.
Interested members of the scientific community should
identify their interest with EPiCC (see How to Contact us
below) and should watch our website for information aboutproposed IOPs.
Our study sites are two Canadian cities with contrasting
climate and long histories of urban climate research: Montréal
and Vancouver. Residential urban and suburban areas are asignificant fraction of the total urban area and are areas for
which TEB-ISBA has not been extensively tested.
The EPiCC network is a multi-year (2006-2010) project of
university and government researchers intended toprovide a version of the TEB-ISBA (TEB - Town Energy
Balance; ISBA - Interactions Soil-Biosphere-Atmosphere)
model (Masson 2000, Noilhan and Planton 1989)optimized and verified for conditions found in Canadian
cities and ready for operational implementation in theCanadian Meteorological Centre numerical prediction
system.
The modeling component includes mesoscale atmospheric modeling and studies of the atmospheric boundary layer as well asdevelopment and evaluation of the TEB-ISBA system. The model system will be evaluated for the winter response of anthropogenic heat
forcing (Montréal) and the summer response of anthropogenic water forcing (through garden irrigation in Vancouver). Development of theTEB hydrological parameterization and advective feedback in the TEB-ISBA coupling are planned.
The observational component is comprised of long term continuous observations of the radiation and energybalance including CO2 concentrations and fluxes in Montréal and Vancouver with seasonal deployment of other
instrumentation. Rural baseline observations are also included.
The remote sensing component includes evaluation and continued development of an urban land use characterization scheme that
provides the surface information necessary for the TEB-ISBA modeling system, use of airborne LiDAR data to help parameterize the
vertical and horizontal structure of urban environments for the modeling system (including both the built and vegetated environment)and use of other ground or space-based remote sensing to assess surface characteristics, especially temperature and snow cover.
