Verification of Urban Heat Island Microclimatic Model by Using Thermal Remote Sensing Data

Abstract

The paper deals with the thermal remote sensing data application in verification of Voronezh urban heat island model. We computed surface temperature layer and temperature variation layer for the warm season of 2015 on the basis of Landsat 8 TIRS scenes set. The values from those layers and the urban heat island layer at 234 ground control areas were compared. It validated the urban heat island model for built-up areas and showed the thermal differences for water and forests surfaces. To convert the real surface temperatures to urban heat island scores a regression model was computed. The study reveals that the thermal remote sensing data and the urban heat island model are complimenting each other in case of microclimatic studies in Voronezh.
