DOES QUALITY CONTROL MATTER? A REVISIT OF SURFACE URBAN HEAT ISLAND INTENSITY ESTIMATED BY SATELLITE-DERIVED LAND SURFACE TEMPERATURE PRODUCTS

Daily mean land surface temperature (LST) acquired from satellite thermal sensors is crucial for various applications such as global and regional climate change analysis. This study proposed a framework to generate global spatiotemporally seamless daily mean LST products (2003–2019). Validations show that the products outperform the traditional method with satisfying accuracy. Our further analysis reveals that the LST-based global land surface warming rate is 0.029 K yr⁻¹ from 2003 to 2019.
