A great example of agricultural remote sensing form the states
On Thursday, October 18th, high winds affected drought-stricken areas of the central high plains as a tight pressure gradient developed between a broad low pressure system in the upper Midwest and a ridge of high pressure centered over the Inter-Mountain West. Surface winds gusting around 50-70 mph were common across an area from the Dakotas through western and central portions of Nebraska and Kansas. With much of this area experiencing exceptional (D4) drought conditions (Figure 1), a large plume of dust was generated mainly in western Nebraska, which then spread rapidly downstream.
West to northwest winds around the base of the broad trough sent the dust plume racing across the mid-Mississippi Valley and into the Tennessee Valley regions overnight. The dust could be seen in visible imagery yesterday afternoon (Figure 2).
However, the dust showed up very well in MODIS Dust RGB imagery (Figures 3-6). Notice the spatial evolution of the dust plume, as it developed…
