Summary

This image uses a combination of <a href="//commons.wikimedia.org/wiki/Category:Infrared" title="Category:Infrared">infra-red</a> and visible light to increase the contrast between water and land. Vegetation appears bright green, water appears navy blue, and clouds appear pale blue-green. the Mississippi River appears swollen near St. Louis. Roughly 175 kilometres north of the city, the <a href="//commons.wikimedia.org/wiki/Category:Illinois_River" title="Category:Illinois River">Illinois River</a> is especially wide compared to the same area in late October. Due east of <a href="//commons.wikimedia.org/wiki/St._Louis,_Missouri" title="St. Louis, Missouri">St. Louis</a>, <a href="https://en.wikipedia.org/wiki/Carlyle_Lake" class="extiw" title="en:Carlyle Lake">Carlyle Lake</a>, along the <a href="https://en.wikipedia.org/wiki/Kaskaskia_River" class="extiw" title="en:Kaskaskia River">Kaskaskia River</a>, has also expanded. Smaller tributaries to the Illinois River also appear flooded. East of the Illinois River, vegetation appears less abundant in early November. The change could be the advance of autumn and/or harvesting of agricultural fields, but differences in angle of sunlight (time of day) between the image acquisitions may also play a role.
