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

Version 005
  • Abstract
    The MODIS/Aqua LST/E L3 Global 1 km Grid (Short name: MYD11B1) products incorporate 6 km pixels (4.63 km pixels for versions prior to V005), 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 MYD11B1 products are a gridded version of the level-2 LST product (MYD11_L2) mapped and projected on 6-kilometer (precisely 5.6 km) Sinusoidal grids. The MYD11B1 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 MYD11_L2 product aggregated to 6 km grids. The V5 Aqua/MODIS LST/E products, including MYD11B1, 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=MYD11 Zhengming, Wan, and Li Zhao-Liang. "A Physics-Based Algorithm for Retrieving Land-Surface Emissivity and Temperature from EOS/MODIS Data." Geoscience and Remote Sensing, IEEE Transactions on 35, no. 4 (1997): 980-96. This product is ready for use in science applications/publications. The V5 collection is not consistent with V4 and V41, and users should exercise caution as they plan to use the different collections.
