ALOS-2/PALSAR-2 Observation Results of Flooding on the Mississippi River
Corresponding to emergency requests from NASA and the International Charter of Space and Major Disasters for flooding of the Mississippi River, the Japan Aerospace Exploration Agency (JAXA) performed an emergency observation over the area shown in figure 1 by means of the Phased Array type L-band Synthetic Aperture Radar-2 (PALSAR-2) aboard the Advanced Land Observing Satellite-2 (ALOS-2, “DAICHI-2”) on January 6, 2016.
Figure 2 is an interactive comparison of the post-disaster image on Jan. 6, 2016 and a pre-disaster image on Sep. 30, 2015. Both images are acquired by high-resolution 10m mode.
