<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN STYLE="font-weight:bold;">Date of Image:</SPAN></P><P><SPAN>Pre-Event: June 2024</SPAN></P><P><SPAN>Post-Event: 9/12/2024, 9/13/2024, 9/14/2024, 9/15/2024</SPAN></P><P /><P><SPAN STYLE="font-weight:bold;">Summary:</SPAN></P><P><SPAN>These Black Marble High-Definition (BMHD) images were created by the NASA Black Marble Science team, with directed funding the NASA-Google Partnership program. The images map the impact of Hurricane Francine on electrical grids in Louisiana. The baseline image is from June 2024, a cloud-free, moon-free composite, and the “after" images are from September 12, 2024 - September 15, 2024. There is a layer to display where clouds are present in the "after" images. This comparison between the images is meant as a visual assessment of outage impacts from the Hurricane 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.</SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">Suggested Use:</SPAN></P><P><SPAN>NOTE: Black Marble HD images are downscaled from NASA’s Black Marble nighttime lights product (VNP46), and as such are a “modelled” or “best guess” estimate of how lights are distributed at a 30m resolution. These images should be used for visualization purposes, not for quantitative analysis.</SPAN></P><P><SPAN /></P><P><SPAN>The image is in inferno color scale. Yellow represents presence of more light; dark blue less lights. Grey represents cloud cover.</SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">Satellite/Sensor:</SPAN></P><P><SPAN>The primary data source, NASA’s Black Marble nighttime lights product suite (VNP46), utilized to generate this product is derived from the Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB) onboard the Suomi National Polar-orbiting Platform (SNPP) along with high resolution base layers - Landsat derived normalized index products (NDVI and NDWI) and OpenStreetMap (OSM) derived road layer</SPAN></P><P /><P><SPAN STYLE="font-weight:bold;">Resolution:</SPAN></P><P><SPAN>Scaled resolution of 30 meters</SPAN></P><P /><P><SPAN STYLE="font-weight:bold;">Credits:</SPAN></P><P><SPAN>NASA Black Marble Science team</SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">Please cite the following two references when using this data:</SPAN></P><P><SPAN>Román MO, Stokes EC, Shrestha R, Wang Z, Schultz L, Carlo EA, Sun Q, Bell J, Molthan A, Kalb V, Ji C.
