    Satellite imagery reveals increasing volatility in human night-time activity: nature.com/articles/s41586-026 -> Satellites capture the glowing pulse of human civilization: news.rub.de/english/press-rele (my contribution to the 2nd image there was rotating - not far enough - and cropping it :-). #ALAN #LightPollution #VIIRS

  15. Acabo de actualizar mi dataset sobre contaminación lumínica nocturna global generado con mi herramienta radiance-geojson (codeberg.org/imigueldiaz/radia). 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: archive.org/details/radiance-g

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

  17. Apparently, between mid-August and now the endpoint we were using to download #VIIRS satellite data from #NASA has disappeared.

    I am trying really, really, really, hard not to discuss political issues in this account, because I would like to make this one all about science, but sheesh.

  18. In 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.

  25. Public 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.

  30. The infamous 'mirrored L' of #LightPollution in western Germany (with Cologne, Düsseldorf, Duisburg, Essen and Dortmund particularly prominent, from bottom to upper left to upper right) as seen by the Chinese #SDGSAT-1 - sdg.casearth.cn/en/mobile/data - and displayed with the online tool pmisson.users.earthengine.app/ which permits zooming and panning. You can either look at the SDGSAT or a #VIIRS DNS layer with less resolution and no color or a map. Now someone please convert this into a sky brightness map!

  33. #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.

  38. 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

  39. NASA/MODIS: " We are pleased to announce that the Suomi-NPP GPS issue, detailed below, has been resolved. So, the processing for SNPP VIIRS NRT data restarts from today July 18 (DOY 2024-200) onwards. " #viirs #RemoteImaging #satellite

  40. VIIRS satellite still having issues and not functioning correctly. (used heavily for wildfire tracking) #VIIRS #RemoteImaging #satellite

  41. Significant, significant difference... used to do this for hurricanes in third world countries with no power reporting, to get ground truth. 😬

    Unfortunately, it appears there has been a GPS geolocation failure on the VIIRS satellite, the 7/11 image is incorrect and they have stopped acquiring images trying to figure out what the problem is. No VIIRS until they fix it or figure out what's going on! #RemoteImaging #VIIRS

  42. Aha, NASA MODIS wildfire layers were all over the map (literally) this morning, it appears there has been some kind of problem with the GPS on the Suomi-NPP satellite. #NASA #RemoteImaging #wildfires #VIIRS #gis

  43. Has happened often enough that it's fairly obvious by now: experimental #EO projects arguably should always include a transition roadmap for operational use, mission overlap etc.

    "The NASA MODIS instruments were originally designed to meet research needs and were never considered as operational; but with their longevity, their use has evolved as they continue to provide long-term data records."

    Leaving a mad scramble of splicing etc. See GRACE et al.
