Abstract
Previous measurements of urban energy balances have been restricted to a small number of cities. This paper presents directly measured energy balance fluxes for suburban areas in four cities within the United States: Tucson, Sacramento, Chicago, and Los Angeles. They represent a range of synoptic regimes and surface morphologies (built and vegetative). Ensemble diurnal patterns and ratios of fluxes for clear, cloudy, and all sky conditions are presented. ...

Abstract
The first measurements of the energy balance fluxes of a dry, densely built-up, central city site are presented. Direct observation of the net radiation, sensible and latent heat flux densities above roof-top in the old city district of Mexico City allow the heat storage flux density to be found by residual. The most important finding is that during daytime, when evaporation is very small (8), the uptake of ...

Abstract
The flux density of sensible heat to or from storage in the physical mass of the city is determined for seven cities (Chicago, IL; Los Angeles, CA; Mexico City, D.F.; Miami, FL; Sacramento, CA; Tucson, AZ; and, Vancouver, BC) in North America across a 30E latitudinal range. These cities have a variety of synoptic-scale climates and surface cover and structural morphologies. In all cases the "measured" storage ...
