MOD11B1_005

MODIS/Terra Land Surface Temperature/Emissivity Daily L3 Global 6km SIN Grid V005

Version 005
  • Abstract
    The MODIS/Terra V5 LST/E L3 Global 1 Km Grid (Short name: MOD11B1) products incorporate 6 km pixels, which are produced daily using the day/night LST algorithm (Wan and Li, 1997). This algorithm extracts average temperatures (in Kelvin) and applies them to a pair of MODIS daytime and nighttime observations. This method yields 1 K accuracy for materials with known emissivities. The six thermal band emissivities are retrieved through the day/night algorithm. The data inputs include the MODIS L1B calibrated and geolocated radiances, geolocation, cloud mask, atmospheric profiles, land and snow cover. The V5 MOD11B1 products are a gridded version of the level-2 LST product (MOD11_L2) mapped and projected on 6-kilometer (precisely 5.6 km) Sinusoidal grids. The MOD11B1 product comprises the following Science Data Set (SDS) layers for daytime and nighttime observations: LSTs, quality control assessments, observation times, view zenith angles, and emissivities from bands 20, 22, 23, 29, 31, and 32. It also includes daytime and nighttime LSTs generated from the 1-km, band 31 of the level-2 MOD11_L2 product aggregated to 6 km grids. The V5 Terra/MODIS LST/E products, including MOD11B1, are validated to Stage-2 through field campaigns and radiance-based validation studies. Further details regarding MODIS land product validation for the LST/E products are available from the following URL: http://landval.gsfc.nasa.gov/ProductStatus.php?ProductID=MOD11 This product is ready for use in science applications/publications. The V5 MOD11B1 product’s acquisition range started March 5, 2000 (2000-065), and continue through March 30, 2017. The V5 collection is not consistent with V4 and V41, and users should exercise caution as they plan to use the different collections.
