   On October 13, 2020, the Moderate Resolution Imaging Spectroradiometer
   (MODIS) on board NASA’s Terra satellite acquired a striking false-color
   image of flooding along the Songhua River and nearby rivers. The
   swollen Nen River can be seen in the west, curving eastward to meet the
   flooded Songhua River. Other tributaries of the Songhua also appear
   above flood stage, including the Di’er Songhua and Lalin rivers, in the
   south.

   This false-color image uses infrared and visible light (MODIS bands
   7,2,1) to help separate water from land and vegetation. Vegetation
   appears bright green, water is deep blue, bare land appears tan, and
   clouds appear white and light blue.

   While a single image shows the situation on a specific day, a
   comparison of two different days can better illustrate the changes
   caused by flooding. Thanks to the NASA Worldview App, it is easy to
   view a roll-over comparison of two Terra MODIS images. To view the
   comparison of the image above, acquired October 15, to an image of the
   same area acquired on July 10, 2020, click  here.

   The NASA Worldview app provides a satellite's perspective of the planet
   as it looks today and as it has in the past through daily satellite
   images. Worldview is part of NASA’s Earth Observing System Data and
   Information System. EOSDIS makes the agency's large repository of data
   accessible and freely available to the public.
