The Impact of Landscape Characteristics on Urban Surface Energy Balance (Research Area 11.1 STIR)
Abstract
The technical objective of the proposed effort is to investigate the impact of landscape characteristics on the urban surface energy balance by quantifying phase lag between land surface temperature and surface heat fluxes. The proposed effort seeks to achieve the stated technical objective using a three-part approach: (1) Develop a mathematical model for the coupled heat and water transport that is applicable to a range of urban environmental conditions. This model will be used to (a) quantify the phase and temporal differences between all urban surface energy budgets (SEBs) and the land surface temperature (LST) and (b) characterize the effect of different urban landscape materials, such as concrete, asphalt, and soils, and vertical water advection on the urban SEB. (2) Validate the model by comparisons to observational data from field measurements. In particular, the PI will obtain datasets comprised of measurements taken under a range of weather conditions, geographic locations, and climatic zones and leveraged by his own urban monitoring campaign, sensor network affiliation, and collaborative research. (3) Assess the impact of phase lags and SEB on building energy efficiency. The numerical model will be applied to assess the impact of different landscape planning strategies of urban mitigation/adaptation via surface energy transport, especially the improvement of building energy efficiency and enhancement of human thermal comfort.
