(EXERCISE - DaNCE March 2026) International Space Station Images for the Brazil Flood May 2024

Date of Images: 05/18/2024 Summary: The visible-wavelength true color RGB digital camera images were taken by astronauts on board the International Space Station showing flooding in southeastern Texas. These images were manually georeferenced by members of the Earth Science and Remote Sensing Unit at NASA Johnson Space Center. Suggested Use: This image provides regional context, and may be useful for visualization of the ongoing event. Higher spatial resolution images may be suitable for spatial analysis to support decision making or research applications. Sensor: Nikon Z9 Electronic Still Camera. Additional Information about the astronaut photography from the ISS.

Dates of Images: Post-Event: May 8, 2024; May 15, 2024 Pre-Event: April 6, 2024; April 21, 2024 Summary: True Color: The True Color RGB composite provides a product of how the surface would look to the naked eye from space. The RGB is created using the red, green, and blue channels of the respective instrument. Color Infrared: The Color Infrared composite is created using the near-infrared, red, and green channels, allowing for the ability to see areas impacted from the fires. The near-infrared gives the ability to see through thin clouds. Healthy vegetation is shown as red, water is in blue. Suggested Use: True Color: provides a product of how the surface would look to the naked eye from space. The True Color RGB is produced using the 3 visible wavelength bands (red, green, and blue) from the respective sensor. Some minor atmospheric corrections have occurred. Color Infrared: depicts healthy vegetation as red, water as blue. Some minor atmospheric corrections have occurred.

Dates of Images: 5/5/2024, 5/6/2025, 5/15/2025 Background: MODIS Global Flood Product, MCDWD, showing flooding observed on 5/5, 5/6, and 5/15/2024 in Rio Grande do Sol, Brazil. Product is based on optical imagery from the MODIS sensor, on both Terra and Aqua spacecraft. Observation times are approximately 10:30 am and 1:30 pm local time; flood extents at other times may not be observed.  The 1-day composite product is delivered here; this uses observations from only the given date. For this event, 5/5/2024 was the first clear day after the weather system passed. By 5/15, substantial flood water was still visible.  Caveats: Flooding is determined by comparing observed water extent to a reference water map, which may be inaccurate in fine details; some "flood" may be expected surface water, and some "surface water" may actually be flood, but both indicate areas where water was detected. The 1-day product can be particularly susceptible to false-positives from cloud shadows, which often can look like water in the source data. This product looks reasonable with few such false-positives, but users are advised to review the optical imagery (Terra and Aqua) in Worldview to confirm (https://go.nasa.gov/globalflood). Worldview also hosts the 2- and 3-day composite products, but not the 1-day delivered here. At 250 m resolution, this product will also not reliably capture flood extents smaller than 250 m.  As this is optical imagery, flooding under clouds will not be detected. Suggested Use: Red in the displayed image indicates flood; blue indicates expected surface water. Satellite/Sensor/Resolution: Terra and Aqua satellites, MODIS sensor, daily 250m resolution data (~10:30 am local time observation for Terra, ~1:30 pm for Aqua) Credits: NRT MODIS/Aqua+Terra Global Flood Product MCDWD_L3_NRT distributed from NASA LANCE.
