      Today’s Image of the Day compares two false-color images of the Indus   
      River and adjacent floodplain in the Sindh province of Pakistan that   
      were acquired by the Moderate Resolution Imaging Spectroradiometer   
      (MODIS) on NASA’s Terra satellite. The top image was acquired on   
      September 22, 2022, and the bottom image on August 28.   
      
      Extreme flooding is obvious in both images, but the comparison shows   
      that some—but far from all—of the recent disastrous flooding has begun   
      to recede. According to the United Nations (UN), on September 20   
      millions of people in Pakistan are still deeply affected by   
      catastrophic flooding, which “is not going anywhere”. It is expected to   
      take six months for the waters to fully recede.   
      
      It is estimated that nearly eight million people have been displaced by   
      monsoonal flooding in Pakistan, which began as early as June. To date,   
      more than 1,500 people have been killed, including 552 children,   
      according to the UN. As often happens after disasters, illness and   
      disease have begun to spread through displaced communities, including   
      cerebral malaria, the most severe form of the disease which is often   
      fatal. Malaria is caused by a parasite that is carried by mosquitoes,   
      which thrive in standing waters after flooding.   
      
      This type of false-color image uses infrared and visible light (MODIS   
      bands 7,2,1) to help distinguish water from land. Water appears various   
      shades of blue, depending on depth and any sediment in the water, with   
      the deepest water looking the darkest. Vegetation looks bright green   
      while open or sparsely vegetated land looks tan. Cloud ranges from   
      white to electric blue.
