MODIS/Terra Thermal Anomalies/Fire 8-Day L3 Global 1km SIN Grid V005

Version 005
  • Abstract
    MODIS Thermal Anomalies/Fire products are primarily derived from MODIS 4- and 11-micrometer radiances. The fire detection strategy is based on absolute detection of a fire (when the fire strength is sufficient to detect), and on detection relative to its background (to account for variability of the surface temperature and reflection by sunlight). Numerous tests are employed to reject typical false alarm sources like sun glint or an unmasked coastline. MOD14A2 data are 8-day fire-mask composites at 1-kilometer resolution provided as a gridded level-3 product in the Sinusoidal projection. Science Data Sets include the fire-mask and algorithm quality. The Terra MODIS instrument acquires data twice daily (10:30 AM and PM), as does the Aqua MODIS (1:30 PM and AM). These four daily MODIS fire observations serve to advance global monitoring of the fire process and its effects on ecosystems, the atmosphere, and climate. Version-5 MODIS Thermal Anomalies & Fire products have attained Validation Stage 3, which was completed using active fire reference data that were derived from ASTER and Landsat-5 TM (30 m resolution) data sources. Change Points of Interest Internal HDF compression reduces products to ~5% of their uncompressed size SDS "most confident detected fire" renamed as "FireMask" Reduced 32-bit QA to simpler 8-bit layer Added global HDF attributes to simplify use of tile-level QA More: Collection 5 Change Summary for MODIS Active Fire Algorithm and Products (http://landweb.nascom.nasa.gov/QA_WWW/forPage/C005_Change_Fire.pdf) V005 Data Set Characteristics: Temporal Coverage: February 26, 2000 - March 29, 2017 Area: ~10 degrees x 10 degrees lat/long File Size: ~0.04 MB Projection: Sinusoidal Data Format: HDF-EOS Image Dimensions: 1200 x 1200 rows/columns Resolution: 1000 meters Science Data Sets (SDS HDF Layers): 2
