MODIS/Terra Land Surface Temperature/3-Band Emissivity 5-Min L2 1km V006

Version 006
  • Abstract
    MODIS/Terra Land Surface Temperature/3-Band Emissivity 5-Min L2 1km (MOD21.006) The MOD21 Land Surface Temperature (LST) and Emissivity swath data product is produced daily in five minute temporal increments of satellite acquisition. The swath is approximately 2,030 pixels along track and 1,354 pixels per line, at a nadir resolution of 1,000 meters. The MOD21 LST algorithm differs from the MOD11 algorithm in that the MOD21 LST algorithm is based on the ASTER Temperature Emissivity Separation (TES) technique, whereas the MOD11 uses the split-window technique. The MOD21 TES algorithm uses a physics-based algorithm to retrieve dynamically both the LST and Emissivity simultaneously from the three MODIS thermal infrared bands 29, 31, and 32. The TES algorithm is combined with an improved Water Vapor Scaling (WVS) atmospheric correction scheme to stabilize the retrieval during very warm and humid conditions. Additional details regarding the method used to create this Level 2 (L2) product are available in the Algorithm Theoretical Basis Document (https://lpdaac.usgs.gov/sites/default/files/public/product_documentation/mod21_atbd.pdf).
