Objective:
Urban microclimates are discrete areas where, as a consequence of urban development, surface temperatures and energy fluxes between the ground and atmosphere may differ from those in nearby regions. Construction materials and other urban landscape features can alter surface radiation components, regional weather and atmospheric flows. The consequences are air and surface temperatures in urban environments that may differ from those in less-developed settings characterized by extensive soil and vegetative cover.
The objective of this project is to document the effects of urban development on the fluxes of energy that act to heat and cool urban surfaces, together with the consequent effects on surface temperature. This is accomplished by combining a set of radiative and meteorological measurements with a quantitative model of the energy balance of the ground. We here describe the measurement sites and instruments, followed by a summary of an energy balance model for application to artificial surfaces. Energy fluxes from solar and terrestrial radiation, sensible heat transport, heat conduction and evaporative cooling are deduced for urban sites with varying characteristics. Comparison of results deduced for different locations illustrates the range of conditions that prevail in various urban microclimates.
