Heat waves and elevated concentration of ambient pollutants constitute two major public health stressors in large metropolitan areas. Both of these stressors may be impacted by future environmental changes, including continued expansion of human-dominated land uses within urban centers and in the surrounding areas. To assess current and future potential public health risks due to heat and air quality changes driven by climate and land use changes in the Kansas City Metropolitan area, an urban micro-meteorological measurement experiment was carried out during the peak warm season months of July and August, 2004. The experiment focused on understanding the controls on sensible heat, latent heat and momentum exchanges at a suburban location recently converted from farmland to a low-density residential sub-division. Measurements of net all-wave radiation; sensible and latent heat fluxes; and a suite of climate parameters were made using an instrumented 30m telescoping mast. This presentation will describe the experiment protocols and report on the observations recorded during the KC-FLUXMEX intensive measurement period. Initial results of urban energy mesoscale modeling studies that incorporate the measured fluxes and associated parameters will also be presented.
