NASA uses satellites to detect fires. The instrument aboard satellites, known as MODIS (Moderate Resolution Imaging Spectroradiometer), can “see” hot spots because fires produce a recognizable type of heat. Whenever satellites detect a hot spot, they flag the signal’s location and add it to a dataset. An algorithm works with the data and can detect a fire about the size of a quarter-acre. There are two satellites orbiting the earth every 98 minutes. Then that information then goes through an algorithm and is sent back about every 2 to 4 hours.
