The MYD11A1 V6 product provides daily land surface temperature
(LST) and emissivity values in a 1200 x 1200 kilometer grid. The
temperature value is derived from the MYD11_L2 swath product. Above
30 degrees latitude, some pixels may have multiple observations
where the criteria for clear-sky are met. When this occurs, the
pixel value is the average of all qualifying observations. Provided
along with both the day-time and night-time surface temperature
bands and their quality indicator layers are MODIS bands 31 and
32 and six observation layers.
