The images map the widespread impact of Hurricane Ida on electric grids within the neighborhoods of New Orleans, LA. The baseline image (before the storm) was from August 9th 2021, a cloud-free, moon-free night, and the “after" image was from August 31st, the day after the storm made landfall in the Gulf of Mexico. This comparison between the two images is meant as a visual assessment of outage impacts from the storm 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.</p><p><span style='font-weight:bold;'>Suggested Use:</span></p><p><span style='font-weight:bold;'>NOTE</span><span>: 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>The image is in inferno color scale.
