V005 MOD11 Changes
V005 MOD11C3 Science Data Sets (specifications for data layers)
V005 MOD11C3 Quality Information

2000 April LST	2007 April LST
Data Set Characteristics: Area: Global Dimensions: 3600 x 7200 rows/columns File Size: ~80MB compressed Resolution: 0.05-degrees (5600-m at the equator) Projection: Lat/Lon LST Data Type: 16-bit unsigned integer Emissivity Data Type: 8-bit unsigned integer Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 17	The false-colored MOD11C3 images shown were retrieved from MODIS data acquired during the same month of different years (April 2000 and 2007). Over the seven year period, subtle differences in monthly temperature are notable, particularly at higher latitudes.

Product Description
The level-3 MODIS global Land Surface Temperature (LST) and Emissivity monthly data are composed from the daily MOD11C1 product and stored as the averaged values of clear-sky LSTs during a monthly period in a 0.05-degree (5600-meter) geographic Climate Modeling Grid (CMG).

MOD11C3 is a level-3 product comprised of daytime and nighttime LSTs, quality assessment, observation times, view angles, bits of clear-sky days and nights, and emissivities retrieved in Bands 20, 22-23, 29, and 31-32.

Version-5 MODIS/Terra Land Surface Temperature/Emissivity products are validated indirectly through the daily 6-km product, MOD11B1, to 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 when monthly averaged LSTs are applications-appropriate.
