V005 MOD11A1 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-color image shows the daytime LSTs under clear-sky conditions in the MOD11A1 product retrieved from daytime MODIS data of 4th April 2000 over the southwestern United States and Baja California.

Product Description
The level-3 MODIS global Land Surface Temperature (LST) and Emissivity daily data include values generated in a Sinusoidally projected tile by mapping the level-2 LST product (MOD11_L2) on 1-kilometer (actual 0.928-km) grids. 

MOD11A1 is comprised of daytime and nighttime LSTs, quality assessment, observation times, view angles, clear sky coverage, and emissivities estimated in Bands 31 and 32 from land cover types.

Version-5 MODIS/Terra 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.
