This example of MOD14A1 displays data from December 5, 2000 along the Gulf of Guinea near eastern Africa leading up the Niger River.  Small yellow and red dots represent fires in the area.

Product Description
The MODerate-resolution Imaging Spectroradiometer (MODIS) Thermal Anomalies/Fire products detect fire locations using 4- and 11-micrometer brightness temperatures. The detection strategy is based on absolute detection, if the fire is strong enough, and on detection relative to the background to account for variability of the surface temperature and reflection by sunlight. Numerous tests are employed to reject typical false alarm sources such as sun glint and unmasked coastline. Because the Terra MODIS instrument acquires data twice daily (10:30 am and 10:30 pm), as does the Aqua MODIS (2:30 pm and 2:30 am), four daily MODIS observations area available to contribute to global fire monitoring.

The MODIS/Terra Thermal Anomalies/Fire Daily L3 Global 1km SIN Grid product, MOD14A1, is one of MODIS' mulitdimensional data products (see also the BRDF/Albedo products). In addition to X- and Y-dimensions, MOD14A1 offers a third dimension providing fire information for each of eight data acquisition days. Specifically, MOD14A1's Fire Mask contains eight, band (day) sequential, 1200 x 1200 images of fire data representing consecutive days of data collection.

The MOD14A1 image above has been pseudo-colored to display one of eight days of fire data. This scene along the Gulf of Guinea near eastern Africa leading up the Niger River on December 5, 2000 depicts low- and nominal-confidence fires as yellow pixels, and high-confidence fires as red pixels.

NOTE: These products are validated, meaning that product uncertainties are well defined over a range of representative conditions. Although there may be later improved versions, these data are ready for use in scientific publications.
