This MODIS dataset (MOD11A2 V6) provides 8-day average land surface temperature (LST) globally at a 1km resolution.
The dataset includes daytime and nighttime LST, quality indicators, emissivity, and observation data.
This dataset has been superseded by a newer version (MODIS/061/MOD11A2) and is considered deprecated.
Data is available from February 18, 2000, to November 9, 2022, and is freely available for use, sale, or redistribution.
Users can explore and analyze this dataset using Google Earth Engine.

Description
The MOD11A2 V6 product provides an average 8-day land
surface temperature (LST) in a 1200 x 1200 kilometer grid. Each
pixel value in MOD11A2 is a simple average of all the corresponding
MOD11A1 LST pixels collected within that 8 day period. The 8 day
compositing period was chosen because twice that period is the
exact ground track repeat period of the Terra and Aqua platforms.
In this product, along with both the day- and night-time surface
temperature bands and their quality indicator (QC) layers, are
also MODIS bands 31 and 32 and eight observation layers.
