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.
