Abstract
Land Surface Temperature (LST) affects urban heat fluxes and is therefore its spatiotemporal patterns is a key parameter in urban microclimatic and energy budget studies. Although LST can be derived from satellite thermal measurements, currently there is no spaceborne instrument to provide frequent thermal imagery at high spatial resolution, which is essential for studying the urban microclimate. In this study, a synergistic algorithm that combines the frequent thermal measurements from Moderate Resolution Imaging Spectroradiometer (MODIS) with the high spatial resolution Landsat-8 imagery for estimating high spatial resolution LST is presented. The developed methodology was applied and high-resolution time series of LST for the case study of Heraklion, Greece were retrieved. The accuracy assessment performed by comparing the derived LST products with Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) LST products, indicated a good agreement.
