In the center of this image is the Solimoes River just west of Manaus before it combines with the Rio Negro to form the Amazon River. The radar image was produced in L-band where red areas correspond to high backscatter at HH polarization, while green areas exhibit high backscatter at HV polarization. Blue areas show low backscatter at VV polarization. The image on the right is a classification map showing the extent of flooding beneath the forest canopy.
Floods are highly episodic and much of the area inundated is often tree-covered.
