MODIS false color images (13 September and 29 September 2010)

A comparison of 250-meter resolution MODIS false color Red/Green/Blue (RGB) images from the SSEC MODIS Today site (above) show dramatic changes in some of the larger rivers (primarily the Mississippi River and the Wisconsin River) before (13 September 2010) and after (29 September 2010) parts of the Upper Midwest region received very heavy rainfall. Two locations in Wisconsin are highlighted where there were evacuations ordered due to flooding: Arcadia (on 23 September) and Portage (on 27 September).

These false color Red/Green/Blue images are created using MODIS bands 7/2/1 — water shows as the very dark features, allowing the changes in river boundaries  (as well as areas that have experienced significant water inundation) to be easily seen.
