description: Data from October 12th onwards can be found here for Hurricane Milton: https://maps.disasters.nasa.gov/arcgis/home/item.html?id=93d2cb2403684275af7c47d468a7be5b Date of Image: Pre-Event: August 2024, September 18, 2024 - September 26, 2024 Post-Event: September 27, 2024 - October 11, 2024 Summary: These Black Marble Day-Night Band (BRDF-Corrected) images were created by the NASA Black Marble Science team. The images corrected for atmospheric, terrain, lunar BRDF, and straylight effects, and directly measures light intensity on the ground in units of nanowatts/(steradian centimeter squared). The images are scaled from 0 - 30, and show the impact of Hurricane Helene on electric grids in the Southeast US. The baseline image is from August 2024, generated from all daily atmospheric and lunar-corrected data from that month, with additional baselines from September 18-25, 2024, and the “after" image from September 27, 2024. There is a layer to display where clouds are present. This comparison between the images is meant as a visual assessment of outage impacts from Francine to aid various partners who are working to deliver emergency aids to local communities. Power outage maps like these help disaster response efforts in the short-term as well as long-term monitoring during the crucial stages of disaster recovery. Suggested Use: NASA's Black Marble Nighttime Light product suite is a state-of-the-art daily global collection of standard products for monitoring nighttime lights (NTL). Utilizing the Visible Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB) aboard the Suomi-NPP, NOAA-20, and NOAA-21 satellites. The image is in inferno color scale. Yellow represents presence of more light; dark blue less lights. Grey represents cloud cover. Satellite/Sensor: Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB) onboard the Suomi National Polar-orbiting Platform (SNPP), NOAA-20, and NOAA-21 SNPP: August 2024 composite, September 18 - 24, 2024, October 1, 20…
