#nighttimelights — Public Fediverse posts

I was really honored to give a talk (remotely) at NASA Goddard today! Thanks for the invitation, and I hope we'll stay in touch!

New today in @Nature: "Our findings challenge the prevailing perspective that changes in light radiance are largely gradual and unidirectional. Instead, the nightlights of Earth are surprisingly dynamic."

And some reporting on the study and its implications by @skyandtelescope: https://skyandtelescope.org/astronomy-news/light-pollution-is-increasingly-volatile-around-the-world/

Sentinel 2 will be taking nighttime acquisitions TONIGHT, and the level 1B data will be available for TWO WEEKS ONLY following the acquisition: https://sentinels.copernicus.eu/web/sentinel/-/sentinel-2-nighttime-imaging-campaign

#ESA commissioned an impact assessment for our Night Watch project, check it out: https://space-economy.esa.int/documents/CCBE0DaUI85rBweWdm0OJKhQpLUMv4SdqfKx8Ovz.pdf

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.

This new paper about variability in #VIIRS DNB data is likely to be interesting to people who work on #RemoteSensing with #NighttimeLights: https://www.sciencedirect.com/science/article/pii/S1569843223003084
