“This tool visualizes near real-time (NRT) satellite-based fire perimeters, active portions of fire perimeters (fire lines), and active fire pixel detections for the current year.
Use the bottom panel to select different date ranges or subset fires by size, duration, or intensity. Click on an individual fire to visualize the time series of fire growth every 12 hours and create video outputs in GIF or WebM formats.
These fire tracking data are from the Fire Event Data Suite (FEDS) algorithm. Find out more:
• FEDS data source documentation
• OpenVEDA documentation
• Earthdata VEDA dashboard..."

Acabo de actualizar mi dataset sobre contaminación lumínica nocturna global generado con mi herramienta radiance-geojson (https://codeberg.org/imigueldiaz/radiance-geojson). Contiene archivos JSON (.json.gz) y un dump completo en PostGIS (restaurada ocupa 27GB, con casi 140 millones de puntos georreferenciados), con datos de radiancia, brillo del cielo y clasificación Bortle para 173 países a 0.5 km de resolución. Basado en imágenes VIIRS de Earth Observation Group, Colorado School of Mines.

Ideal para análisis geoespaciales, ambientales y astronómicos, en mi caso lo usaré para astrofotografía si me da la vida. Licencia CC BY 4.0.

Dr. John Barentine FRASIn order to fully understand how #LightPollution affects our world, we need to know how much of it is in which places. Divergent results from different measurement methods present some tension, but recent research suggests a way forward.

Last night's nighttime view of Spain/Portugal before their power outage. (VIIRS Day/Night Band)
Tokyo seen on VIIRS DNB Nighttime Imagery on Feb 11, 2025. That city sure has a lot of light! #Tokyo #RemoteImaging #VIIRS
Christopher KybaPublic service announcement:
Data from #VIIRS DNB since the summer is affected by an instrumental effect, which makes the data from the last few months darker than they should be (see e.g. this graph for Manhattan). The #NASA #BlackMarble team is working to fix it.
ht to Damien Guiraudie who wrote to me to ask what was going on, and also to Zhuosen Wang from @NASA who quickly responded to my question.
