One generates linear streaks with approximately a 10-30 meter wavelength perpendicular to the streaks. We have considered several possible explanations for these observations. For example artifacts of the scanner, artifacts of the crop rows, artifacts of look angle or some combination of these. The same patterns are equally visible in many of the fields at the farm. The track of the scanner's sweep is oblique to the average trend of the streaks.
Various fields have differing row orientations.
The crops involved include soybeans, cotton and peanuts. The 4 images are taken from just two views, as the aircraft flew nearly identical tracks on the repeat flights. The patterns cross field boundaries. We think this is a response to wind. Wind is the only phenomena which can change this rapidly and on such a small spatial scale and affect a variety of crops several kilometers apart.
