For comparison of what the storm looked like from the top down, the top image from NASA's Aqua satellite reveals Ike's eye in the middle of the storm. It was created using data from the Advanced Microwave Scanning Radiometer-EOS (AMSR-E). Over the ocean, AMSR-E microwave frequencies measure the microwave emissions from larger raindrops. The red line through the image shows the vertical cross section through Ike. The blue areas along the top of the clouds indicate cloud ice, while the wavy blue lines on the bottom center of the image indicate intense rainfall. Notice that the solid line along the bottom of the panel, which is the ground, disappears in this area of intense precipitation. It is likely that in the area the precipitation rate exceeds 1.18 inches/hr based on previous studies.
