This comparison image shows flooding in the Northern Territory of Australia on March 13, 2024. The left image (A side) is a corrected reflectance (Bands 7-2-1) image from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard the Terra satellite, which shows flooded areas in shades of blue.
The right image (B side) uses the same band combinations as the left image with the addition of the Flood (3-Day Window) layer, which shows flooded areas in red. The Flood (3-Day Window) layer is created from data acquired by the MODIS instrument aboard both the Terra and Aqua satellites and requires three water detections over three days to mark an area as having a flood.
Swipe the bar back and forth to see how the left side (A side) image showing floodwaters in shades of blue corresponds with the floodwaters highlighted by the Flood (3-Day Window) layer in the right image (B side).
