anthropogenic heat q f context and objective

ANTHROPOGENIC HEAT: QFContext and Objective

CONTEXT:

Additional Source of Energy in Urban Areas

Factor of Urban Heat Island (UHI)

Release’s Sources:

Traffic Vehicles

Energy Consumptions in Residential, Commercial and

Industrial Sectors

Input in the Surface Energy Balance (TEB)

OBJECTIVE:

Need Fluxes in Spatial-Temporal Resolution of Urban

Atmospheric Model (urbanGEM)

Build Hourly Anthropogenic Fluxes on Model’s Grid

ANTHROPOGENIC HEAT: QFStatus and Future Work

CURRENT STATUS

Case of Oklahoma City, JU2003, Ready

FURTHER WORK

Implementation in the Model urbanGEM

Evaluate the domestic heating parameterization in TEB

Quantify the impact of anthropogenic fluxes on the urban

microclimate and on the boundary layer

Improve the estimation of anthropogenic fluxes’

Strategy

Data Energy acquisition for Montreal and Vancouver

Provide the Anthropogenic Data Base
