Agricultural burning continues across the Central Plains of the United States on April 4, 2004. The fires, detected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite have been marked with red dots in this image. The fires are concentrated in Kansas and Oklahoma (top left and bottom left), with additional fires in Missouri and Arkansas (top right and bottom right).
The widespread nature of the fires and their location (generally located away from remaining natural vegetation, which appears deeper green) suggests that these fires are being set intentionally for agricultural purposes. Though not necessarily hazardous, such large-scale burning can have an impact on weather, climate, human health, and natural resources.
Two large rivers flow from west to east across the scene. The Missouri River runs out of Kansas into Missouri through Kansas City, which sits right on the border of the two states. To the south, the Arkansas River flows out of Oklahoma into Arkansas where it weaves between the Boston Mountains, which appear reddish brown, and the Ouachita Mountains, whose ridges are deep brown and punctuated by green valleys.
