Description

The MYD11A2 V6.1 product provides an average 8-day land surface temperature (LST) in a 1200 x 1200 kilometer grid. Each pixel value in MYD11A2 is a simple average of all the corresponding MYD11A1 LST pixels collected within that 8 day period. The MYD11A2 does a simple averaging of all daily LST values, without any filtering for specific QA bits. Each of the MYD11A2 QA values are set based on what majority of input daily QA values are for any given pixel.

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.
