Product Description
MOD14A1 is one of MODIS' 3-D data products. In addition to X- and Y-dimensions, Level 3 Daily fire products include 8 separate days of data detailing pixels according to their level of confidence as fires. The Fire Mask contains eight, band (day) sequential, 1200 x 1200 images of fire data representing consecutive days of data collection. The images above have been pseudo-colored to display one of the eight days of fire data in a granule of MOD14A1.
The Terra MODIS instrument acquires data twice daily (10:30 am and 10:30 pm), as will the Aqua MODIS (2:30 pm and 2:30 am). These four daily MODIS observations will advance global fire monitoring with 1 km resolution fire channels centered at the 4 and 11 micrometer wavelengths. MODIS data will also be used to monitor burn scars, vegetation type and condition, smoke aerosols, water vapor and clouds for overall monitoring of the fire process and its effects on ecosystems, the atmosphere, and climate. A data base of active fire products will be generated and archived at 1 km resolution and summarized on a grid of 10 km and 0.5° latitude/longitude at daily, 8-day, and monthly intervals. It includes the fire occurrence and location, the rate of emission of thermal energy from the fire and a rough estimate of the smoldering/flaming ratio. This information will be used in monitoring the spatial and temporal distribution of fires in different ecosystems, detecting changes in fire distribution and identifying new fire frontiers, wild fires, and changes in the frequency of the fires or their relative strength.
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.
