8-day average land surface temperature at 1km (Copernicus)
What it measures. Reports the average daytime and nighttime ground-surface temperature over each eight-day window at 1-kilometre detail, plus how surfaces emit heat.
How it's made. Created by averaging the daily Aqua MODIS land-temperature readings from NASA into 8-day composites on a 1-kilometre grid.
How & where you'd use it. A smoother, gap-reduced view of surface heat ideal for tracking seasonal trends, drought, and climate patterns over time.

Official description
The MODIS Aqua MYD11A2 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 × 1,200 km grid. Each pixel value represents the simple average of all corresponding MYD11A1 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.
