The fires are shown as tiny particles with each particle depicting the site at which a fire was detected. Daily fires are displayed at a rate of 10 days per second. The fire particles fade over 1.7 seconds and change color as they age from red to orange, yellow and gray. A clock inset indicates the date. Note: This animation shows fires detected over North America from 8-21-2001 through 8-20-2002 with a clock inset. Data Collected: 2001/08/21 through 2002/08/20.
