Correlation of Land Surface Temperature with IR Albedo for the Analysis of Urban Heat Island
Paula Andrés-Anaya, María Sánchez-Aparicio, Susana Del Pozo, S. Lagüela
Abstract
Albedo and Land Surface Temperature (LST) are thermophysical parameters that define the behavior of cities in terms of Urban Heat Islands (UHIs). Both parameters are correlated in such a way that materials with low values of albedo (associated with low reflection rates of solar radiation) result in higher heat absorption, and consequently, in higher LST values. This tendency reinforces the effect of UHI. Thus, the use of materials with high values of albedo in building envelopes can be a solution to reduce heat accumulation within cities and to subsequently improve the temperature reduction at nighttime.
