i have a plan to conduct surface urban heat island / land surface temperature study. Which of the Thermal bands to use when calculating temperature from a sentinel imagery?which one is more advanced from Landsat and sentinel?
Sentinel-2 dose not have Thermal band. However you may use Sentinel-3 SLSTR data. Please see the specification at https://sentinel.esa.int/web/sentinel/technical-guides/sentinel-3-slstr/instrument/specifications
