The MODIS Terra MOD11A2 Version 6.1 product provides an 8-day composite of per-pixel Land Surface Temperature and Emissivity (LST&E) at 1 km spatial resolution, distributed in a 1,200 Ã 1,200 km grid. Each pixel value represents the simple average of all corresponding MOD11A1 LST observations acquired during the 8-day compositing period. The product includes both daytime and nighttime surface temperature bands, along with associated 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. The 8-day compositing interval corresponds to half of the exact ground track repeat cycle of the Terra and Aqua satellites.
