Dates of Imagery: 8/21 - 9/16/2019 Next Estimated Update: None Expected Refresh Interval: 24 Hours Summary: From the NASA Black Marble product suite, the images of nighttime lights in Hurricane Dorian ROI areas are based on data captured by the Suomi NPP satellite, with an equator crossing time of approximately 1:30 am local time. The data was acquired by the Day/Night Band (DNB) of the Visible Infrared Imaging Radiometer Suite (VIIRS), which detects light in a range of wavelengths from green to near-infrared, including city lights and lights from other activity. The NASA Black Marble standard product is available on a daily basis within 3-5 hours after acquisition at 500m spatial resolution from January 2012 to present. Suggested Use: In this image, city lights appear in bright shades of yellow to white when not obscured by clouds (shades of blue to white). Visual comparisons of pre- and post-event scenes allow for subjective identification of where lights are missing as a result of disaster impacts on local infrastructure that have caused damages to structures or utilities. Satellite/Sensor: Suomi National Polar-Orbiting Partnership (S-NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) use of the day-night band and M15 thermal infrared band. S-NPP is a joint mission between NASA and NOAA. Similar capabilities are available from the NOAA-20 mission.
