Calculation methods | - Zhou et al. (2021): We used LST data derived from the thermal infrared (TIR) band (10.40–12.50 mm) of Landsat-5 Thematic Mapper (TM) images with a spatial resolution of 120 m. We used a total of 34 TM images, most of which were acquired in the summer of 2010 (June, July or August) to coincide with the year the census data were collected. All the images were acquired on sunny, calm days with clear-sky conditions at approximately 10:30 a.m. local time. We first converted the digital number of the TM TIR band to the top-of-atmospheric (TOA) radiance. We then calculated the surface-leaving radiance from TOA radiance. This was carried out by removing the effects of the atmosphere in the thermal region. Finally, we calculated LST based on surface-leaving radiance using the Planck function. More details about the calculation of LST can be found in Zhou et al. (2014)
