Summary:
These Black Mable High-Definition (BMHD) images were created by the USRA/NASA Black Marble Science team, with directed funding the NASA-Google Partnership program. The images map the widespread impact of Hurricane Otis on electric grids across Acapulco, Mexico. The baseline image (before the storm) was from October 13, 2023, a cloud-free, moon-free night, and the “after" image was from October 29, 2023. There is a layer to display where clouds are present in the "after" imager. 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.
Suggested Use:
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.
The image is in inferno color scale. Yellow represents presence of more light; dark blue less lights.
Satellite/Sensor:
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
Resolution:
Scaled resolution of 30 meters
