Summary

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. MOD14A1 is produced every 8 days at 1-kilometer resolution as a gridded level-3 product in the Sinusoidal projection. This product is unique in that it has three dimensions: fire-mask (1D) and a maximum fire-radiative-power (2D) are provided for each day (3D) in the 8-day period. For example, the fire-mask contains eight, band sequential (day) 1200 x 1200 images of fire data representing consecutive days of data collection. The Terra MODIS instrument acquires data twice daily (10:30 AM and PM), as does the Aqua MODIS (2:30 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 V005 Data Set Characteristics: Area: ~10 degrees x 10 degrees lat/long Image Dimensions: 1200 x 1200 rows/columns File Size: ~0.5MB Resolution: ~1000 meters Projection: Sinusoidal Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 4 + Vdata Table V004 Data Set Characteristics (decommissioned): Area: ~10 degrees x 10 degrees lat/long Image Dimensions: 1200 x 1200 rows/columns File Size: ~55MB Resolution: ~1000 meters Projection: Sinusoidal Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 2 V003 Data Set Characteristics (decommissioned): Area: ~10 degrees x 10 degrees lat/long Image Dimensions: 1200 x 1200 rows/columns File Size: ~50MB Resolution: ~1000 meters Projection: Integerized Sinusoidal Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 2 |
