A new method to quantify surface urban heat island intensity

Science of The Total Environment, 2018
Reliable quantification of urban heat island (UHI) can contribute to the effective evaluation of potential heat risk. Traditional methods for the quantification of UHI intensity (UHII) using pairs-measurements are sensitive to the choice of stations or grids.

Urbanization Effects on Vegetation and Surface Urban Heat Islands in China’s Yangtze River Basin [PDF]

Remote Sensing, 2017
In the context of rapid urbanization, systematic research about temporal trends of urbanization effects (UEs) on urban environment is needed. In this study, MODIS (Moderate Resolution Imaging Spectroradiometer) land surface temperature (LST) data and enhanced vegetation index (EVI) data were used to analyze the temporal trends of UEs on vegetation and ...
