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 Land Surface Temperature (LST) algorithm differs from the MOD11 (https://doi.org/10.5067/modis/mod11_l2.061) 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. Additional details regarding the method used to create this Level 2 (L2) product are available in the Algorithm Theoretical Basis Document (ATBD (https://lpdaac.usgs.gov/documents/107/MOD21_ATBD.pdf)). \r\n\r\nThe Version 6.1 Level-1B (L1B) products have been improved by undergoing various calibration changes that include: changes to the response-versus-scan angle (RVS) approach that affects reflectance bands for Aqua and Terra MODIS, corrections to adjust for the optical crosstalk in Terra MODIS infrared (IR) bands, and more.", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://irsa.ipac.caltech.edu/SCS?table=sdwfs_ch2_epoch3&", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://irsa.ipac.caltech.edu/data/SPITZER/SDWFS/gator_docs/sdwfs_colDescriptions.html", "format": "HTML", "mediaType": "text/html"}], "identifier": "10.5067/MODIS/MOD21.NRT.061", "keyword": ["earth-science-surface-radiative-properties-land-surface-emissivity", "earth-science-surface-thermal-properties-land-surface-land-surface-temperature"], "license": "https://www.usa.gov/government-works", "modified": "2026-08-17", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/GSFC/EOS/ESDIS/LANCE MODIS"}, "spatial": "[\"CARTESIAN\", [{\"NorthBoundingCoordinate\": 90, \"WestBoundingCoordinate\": -180, \"EastBoundingCoordinate\": 180, \"SouthBoundingCoordinate\": -90}]]", "theme": ["Earth Science"], "title": "MODIS/Terra Land Surface Temperature/3-Band Emissivity 5-Min L2 1km NRT"}
