The Effect of Rain and Flooding Events on AMSR-E Signatures of La Plata Basin, Argentina
The objective of this paper is to describe and explain the effects on selected AMSR-E channels of two strong events, i.e., a rainstorm and a flooding, occurred in the Argentine section of La Plata basin. More specifically, the rainstorm took place within the Chaco region, which is covered by a conti...
