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/Aqua Thermal Anomalies/Fire Daily L3 Global 1km SIN Grid product, MYD14A1, is one of MODIS' mulitdimensional data products (see also the BRDF/Albedo products). In addition to X- and Y-dimensions, MYD14A1 offers a third dimension providing fire information for each of eight data acquisition days. Specifically, MYD14A1's Fire Mask contains eight, band (day) sequential, 1200 x 1200 images of fire data representing consecutive days of data collection.

The MYD14A1 image shown is an example of the Level 3 Daily Thermal Anomalies/Fire product, MYD14A1. The lower image displays a subset of the top left corner of the upper image to emphasize fire pixels, which are classified according to the table above. The data were acquired on February 8, 2004 in the Llanos region in Venezuela and Columbia where agricultural management burns were occurring.

NOTE: These products are provisional, meaning that product quality may not be optimal. Incremental product improvements are still occurring, and users are urged to contact MODIS Science Team representatives prior to use of the data in publications. These data are likely to be replaced when the validated product becomes available.
