V005 MYD11B1 Quality Information

	Data Set Characteristics: Area: ~1100 x 1100 km Dimensions: 200 x 200 rows/columns File Size: ~0.2 MB compressed Resolution: 6-kilometer (5.6-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): 18
	The above false-color image shows the daytime LSTs under clear-sky conditions in the MYD11B1 product retrieved from MODIS data of 9 May 2007 over the southwestern United States.

Product Description
The level-3 MODIS global Land Surface Temperature (LST) and Emissivity daily data are retrieved at 6-kilometer (actual 5.6-km) grids in a Sinusoidally projected tile by the day/night LST algorithm from pairs of MODIS daytime and nighttime observations in seven bands under certain conditions. 

MYD11B1 is comprised of the 5.6-km daytime and nighttime LSTs, quality assessment, observation times, view angles, and emissivities retrieved in Bands 20, 22-23, 29, and 31-32.  MYD11B1 also includes the daytime and nighttime LSTs generated from the level-2 MYD11_L2 through the 1-km Band 31 radiance values aggregated to 5.6-km grids.

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.
