The MODIS maps display the Moderate Resolution Imaging Spectroradiometer (MODIS) fire detection data, which is collected via satellite. Thermal data, for the northern hemisphere, is collected twice a day, at 12:00 AM EST and 2:00 PM EST. Color Coding Legend: Red Circles: fire activity within the last 0-12 hours Orange Circles: fire activity within the last 12-24 hours Yellow Circles: Fire activity within the last 24-48 hours Burn area and perimeter lines of current fires are usually shown in yellow, though occasionally for some fires they are green. Perimeter lines of previous fires from this fire season are shown in gray.
