MODIS/Terra Near Real Time (NRT) Thermal Anomalies/Fire 5-Min L2 Swath 1km (C005)
Entry ID: MOD14


Summary
Abstract: MODIS Near Real Time (NRT) 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.MOD14 is level-2 swath data provided daily at 1-kilometer resolution. The Science Data Sets in this product include fire-mask, algorithm quality, radiative power, and numerous layers describing fire pixel attributes.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.V005 Data Set Characteristics: Area: ~2330 x 1300 km Image Dimensions: 2030 x 1354 rows/columns File Size: ~0.4 MB Resolution: 1 kilometer Projection: None (swath data) Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 23 V004 Data Set Characteristics (decommissioned): Area: ~2330 x 2000 km Image Dimensions: 2030 x 1354 rows/columns File Size: ~0.4 MB Resolution: 1 kilometer Projection: None (swath data) Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 22 V003 Data Set Characteristics (decommissioned): Area: ~2330 x 10 km Image Dimensions: 2030 x 1354 rows/columns File Size: ~53 MB Resolution: 1 kilometer Projection: None (swath data) Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 18V001 Data Set Characteristics (decommissioned): Area: ~2330 x 10 km Image Dimensions: 2030 x 1354 rows/columns File Size: ~53 MB Resolution: 1 kilometer Projection: None (swath data) Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 18

Quality
Overall NRT products match to operational with some expected minor differences from use of different ancillaries and ephemeris. There aren't any data gaps or data artifacts.
