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.

Puedes descargarlo gratis desde: https://archive.org/details/radiance-geojson-data-2025

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

Hmm, satellite hotspots in Southern Lebanon over the last 7 days 👀 #Lebanon #RemoteImaging #VIIRS #MODIS

#NASA hat mit dem #GEOS-Modell eine beeindruckende globale Karte des #CO2-Ausstoßes erstellt. Das hochauflösende #Wettermodell nutzt #Supercomputer und Milliarden von Datenpunkten, um atmosphärische Ereignisse wie #Stürme und #Wolkenformationen darzustellen. Das Modell zieht Daten von #Erdbeobachtungen und #Satelliteninstrumenten, darunter #MODIS und #VIIRS, heran und liefert eine Auflösung, die über 100 Mal höher ist als die typischer Wettermodelle.

A brand new NASA video reveals the fascinating patterns of carbon dioxide moving around our atmosphere.

The visualization shows #CO2 pouring out from major cities in the U.S., before being blown into swirling eddies by atmospheric currents.

The video, which shows the CO2 patterns between January and March 2020, was created using a model named the Goddard Earth Observing System ( #GEOS ),

which uses supercomputers to simulate the atmosphere based on data from satellite instruments including the Terra satellite's #MODIS and the Suomi-NPP satellite's #VIIRS, as well as ground observations
