Lights Out

Scientist Miguel Román and colleagues combined NASA's Black Marble night lights data product from the NASA/NOAA Suomi National Polar-orbiting Partnership with data from USGS-NASA Landsat satellites and other sources to produce a neighborhood-scale map of energy use in communities across Puerto Rico as electricity was restored after Hurricane Maria in 2017.Complete transcript available.Watch this video on the NASA Goddard YouTube channel.

In Puerto Rico, during Hurricane Maria, the entire island's lights went out. In the days, weeks, and months that followed, research physical scientist Miguel Román at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and his colleagues combined NASA's Black Marble night lights data product from the NASA/NOAA Suomi National Polar-orbiting Partnership satellite with USGS-NASA Landsat data and Google's OpenStreetMap to develop a neighborhood-scale map of energy use in communities across Puerto Rico as the electricity grid was slowly restored. They then analyzed the relationship between restoration rates in terms of days without electricity and the remoteness of communities from major cities.En Español:Por la noche, las vistas de la Tierra captadas por satélites se iluminan, mostrando brillantes collares consistentes de carreteras salpicadas por ciudades y pueblos que se asemejan a relucientes perlas. Las actividad humana, reflejada en el uso de luces artificiales, toma un papel protagonista. En Puerto Rico, durante el Huracán María, todas las luces de la isla se apagaron.En los días, semanas y meses que siguieron, el investigador Miguel Román del Centro de Vuelo Espacial Goddard de la NASA en Greenbelt, Maryland, y sus colegas combinaron el producto de datos de luces nocturnas Black Marble de la NASA, proveniente del satélite Suomi National Polar-orbiting Partnership de la NASA y NOAA, con datos del satélite Landsat de USGS-NASA y con OpenStreetMap de Google. Usando todos estos datos, los investigadores crearon un mapa que mostraba el uso de energía a nivel de vecindad en comunidades de todo Puerto Rico a medida que la red eléctrica iba siendo lentamente reestablecida. A continuación, analizaron la relación existente entre los niveles de restablecimiento (en términos de días sin electricidad) y la lejanía de las comunidades respecto a los grandes centros urbanos.

This visualization starts with a global view of hurricane Maria hitting Puerto Rico. We then zoom in to Puerto Rico to compare the standard night lights dataset to a new, high definition version of nights lights. After the hurricane passes over the island, we see a massive drop in night light intensity due to loss of power. After showing night light levels over several stages of hurricane recovery, we transition to a 'Days Without Power' dataset. The camera then zooms in to several locations around the island to examine each stage of recovery in more detail. This visualization starts with a global view of hurricane Maria hitting Puerto Rico.
