The MODIS Terra MOD11A1 Version 6.1 product provides daily per-pixel Land Surface Temperature and Emissivity (LST&E) at 1 km spatial resolution. The data are generated from the MOD11_L2 swath product and distributed on a 1,200 à 1,200 km grid. Pixel temperature values are derived from clear-sky observations; at latitudes above 30°, where multiple clear-sky observations may occur within a day, the pixel value represents the average of all qualifying measurements. The product includes both daytime and nighttime surface temperature bands, along with quality control layers, observation times, view zenith angles, clear-sky coverage information, and emissivity estimates for MODIS Bands 31 and 32 derived from land cover types.
