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.", "items": [], "extra_data": {} }, { "id": 324713, "url": "https://svs.gsfc.nasa.gov/12616/#media_group_324713", "widget": "Video player", "title": "", "caption": "", "description": "Música: Formulas and Equations, Richard Andrew Canavan

NASA scientists studied the island's forests before and after the storm. Goddard's Lidar, Hyperspectral, and Thermal Imager (G-LiHT) is a portable instrument that maps forest health and structure from a small airplane resulting in detailed 3-D views of the forest. G-LiHT sends out 600,000 laser pulses every second mapping leaves and branches, rocks and streams. Almost 60% of the canopy trees lost branches, snapped in half, or were uprooted. Trees with wide, spreading crowns were reduced to a slender main trunk. Forests in Puerto Rico are now one-third shorter on average, after Hurricane Maria. The disturbances affected the whole ecosystem, from soils and streams to birds and frogs. G-LiHT data will help scientists understand how forests and wildlife respond to future changes. || SIGGRAPH_lidar_over_Puerto_Rico.01000_print.jpg (1024x576) [90.3 KB] || SIGGRAPH_lidar_over_Puerto_Rico.01000_searchweb.png (320x180) [89.6 KB] || SIGGRAPH_lidar_over_Puerto_Rico.01000_thm.png (80x40) [7.1 KB] || SIGGRAPH_PuertoRicoLidar.webm (1920x1080) [19.9 MB] || SIGGRAPH_lidar_over_Puerto_Rico.webm (1920x1080) [21.4 MB] || SIGGRAPH_PuertoRicoLidar.mp4 (1920x1080) [253.0 MB] || ", "release_date": "2019-07-29T18:30:00-04:00", "update_date": "2023-05-03T13:45:45.769286-04:00", "main_image": { "id": 398514, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a004700/a004735/SIGGRAPH_lidar_over_Puerto_Rico.01000_print.jpg", "filename": "SIGGRAPH_lidar_over_Puerto_Rico.01000_print.jpg", "media_type": "Image", "alt_text": "Hurricane Maria transformed the lush rainforests of Puerto Rico leaving lots of openings in the forest canopy.

During Hurricane Maria, Puerto Rico'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. || ", "release_date": "2018-12-09T00:00:00-05:00", "update_date": "2025-01-13T00:11:00.842030-05:00", "main_image": { "id": 398084, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a004600/a004658/bmhd_11_0940_print.jpg", "filename": "bmhd_11_0940_print.jpg", "media_type": "Image", "alt_text": "This visualization starts with a global view of hurricane Maria hitting Puerto Rico.

After showing night light levels over several stages of hurricane recovery, we transition to a 'Days Without Power' dataset.
