V005 MOD14 Quality Information

Data Characteristics Area: ~2330 x 1300 kilometers Dimensions:  2030 x 1354 rows/columns File Size: ~0.4 MB Resolution: 1 kilometer Projection: None (swath data) Fire Mask Data Type: 8-bit unsigned integer Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 23 Dimensions: 3 ( row x column x Fire Pixel Table)	MODIS level-2 fire data acquired March 8, 2007 were used to create these images.  Pixels are color-coded using the MOD14 Fire Mask to highlight fires in yellow, water bodies in blue, and clouds in cyan, while land areas are left black.  The top left image is a subset of the full swath on the right.  The subset is centered to the south along the Florida Panhandle between Panama City and Tallahassee, and shows several of the prescribed fires burning throughout the southern U.S. on that date. The lower left image is a plot in megawatts of the Fire Radiative Power (FRP) values reported for the 283 fire pixels identified with yellow in the swath.  FRP is included in the MOD14 product’s Fire Pixel Table.

V005 Change Points of Interest:

• Changed calculation of fire radiative power (FRP) to produce more useful output; users no longer need to multiply FRP by pixel area.
• Changed long name of SDS "FP_power".
• Changed calculation of detection confidence to more accurately identify questionable fire pixels.

Product Description
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.

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.

Version-5 MODIS/Terra Thermal Anomalies/Fire products are Validated Stage 1, meaning that accuracy has been estimated using a small number of independent measurements obtained from selected locations and time periods and ground-truth/field program efforts.  Although there may be later improved versions, these data are ready for use in scientific publications.
