the modis fire products

2008-5-15 · MODIS active fire products provide a valuable source of data about fire activity that capture spatial and temporal patterns not represented in other fire data. Based on our analysis, overall detection rates of fires by the MODIS active fire products were high (82%) when data from both the Aqua and Terra sensors were combined.


Early in the mission, the MODIS Science Team decided to maintain a record of multiple data versions of Aqua- and Terra-derived MODIS products from a unique temporal bracket. Called the “Golden Month,” it covers 40 days of acquired data and all derived products from August 29, 2002 to October 7, 2002 (2002-241 to 2002-280).
