MODIS Land Surface Temperature and Emissivity
Land surface temperature (LST) is a key parameter in the physics of land surface processes at regional and global scales, combining the results of all surface–atmosphere interactions and energy fluxes between the atmosphere and the ground (Mannstein 1987; Sellers et al. 1988). The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra and Aqua platforms produce high-quality LST products from data, which possess a number of strengths. They include global coverage, high radiometric resolution and wide dynamic ranges, accurate geolocation (Wolfe et al. 2002), and high-quality thermal infrared (TIR) calibration accuracy used in the LST retrieval (Barnes et al. 1998).
