The beginnings of disaster assessment and recovery are underway across the Philippines following the landfall of Super Typhoon Haiyan late last week. As the storm approached landfall, several dramatic perspectives were provided from a variety of satellites, including the Japanese Meteorological Agency’s MTSAT (geostationary), NASA’s MODIS instruments, the Tropical Rainfall Measurement Mission, and the Visible Infrared Imager Radiometer Suite (VIIRS) aboard the Suomi National Polar-Orbiting Partnership. As shown here before, the VIIRS has a unique capability provided by the day night band, which detects light from fires, cities, and reflectance of moonlight when the moon is well-lit and visible in the night sky. SPoRT continues to explore applications of the day-night band, including quantitative approaches to identifying impacts from major disasters. By comparing current observations to a trusted baseline, we can attempt to gauge the “percent of normal light” being emitted by a location. Sudden drops in emitted light from known, populated areas are likely due to damaged infrastructure as long as clouds are not obstructing a view of the surface. Here are some examples of this approach as applied to the Philippines, using data from November 9 in comparison to the NOAA/NASA “Black Marble” composite of clear sky “average” light emissions. As the region begins to recover, light emissions can be monitored as a very high-level metric for ascertaining progress. Similar applications were developed by the SPoRT Center following Superstorm Sandy.
