V005 MYD14A2 Quality Information

Data Characteristics Area: ~10 degrees x 10 degrees Dimensions: 1200 x 1200 rows/columns File Size: ~0.4 MB Resolution: 1 kilometer Projection: Sinusoidal Fire Mask Data Type: 8-bit unsigned integer Data Format: HDF-EOS Science Data Sets (SDS HDF Layers): 2

The images above represent fires identified between May 1 - 8, 2007, an 8-day period during which the northern plains of the U.S. experienced numerous wildfires attributed to prolonged drought conditions. Using the MYD14A2 Fire_Mask a color code was applied to highlight fires in yellow, water bodies in blue, and leaving land area in black. Each yellow pixel is 1km2. The image on the left is the entire tile h11v04 along the Canadian border with North Dakota, Minnesota, and Wisconsin. Zooming in on the upper left quadrant of the tile, prominent fires surround North Dakota's Lake Sakakawea, a reservoir along the Missouri River.

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.

MYD14A2 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 Aqua MODIS instrument acquires data twice daily (1:30 PM and AM), as does the Terra MODIS (10:30 AM and PM). 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/Aqua 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.
