V005 MYD11A2 Quality Information

	Data Set Characteristics: Area: ~1100 x 1100 km Dimensions: 1200 x 1200 rows/columns File Size: ~4 MB compressed Resolution: 1-kilometer (0.93-km) Projection: Sinusoidal LST Data Type: 16-bit unsigned integer Emissivity Data Type: 8-bit unsigned integer Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 12
	The above false-colored MYD11A2 image shows the 8-day average values of daytime clear-sky LSTs retrieved from MODIS data in the period of May 9 – 16, 2007 over the southwestern coast of the United States.

Product Description
The level-3 MODIS global Land Surface Temperature (LST) and Emissivity 8-day data are composed from the daily 1-kilometer LST product (MYD11A1) and stored on a 1-km Sinusoidal grid as the average values of clear-sky LSTs during an 8-day period. 

MYD11A2 is comprised of daytime and nighttime LSTs, quality assessment, observation times, view angles, bits of clear sky days and nights, and emissivities estimated in Bands 31 and 32 from land cover types. 

Version-5 MODIS/Aqua Land Surface Temperature/Emissivity products are Validated Stage 1, meaning that accuracy has been estimated using a small number of independent measurements obtained from selected locations and time periods and ground-truth/field program efforts.  Although there may be later improved versions, these data are ready for use in scientific publications.
