End of an Era: Landsat 7 Decommissioned After 25 Years of Earth Observation After 25 years of capturing Earth's changing landscape, the Landsat 7 satellite received its final transmission from the U.S. Geological Survey and was officially decommissioned June 4, closing a rema...

USGS, which operates the Landsat satellites, just announced that Landsat 7 was officially decommissioned today. Landsat 8 and 9 continue operations.

Également dans @mariannelemag.bsky.social (le "print"), le portrait d'un chercheur suisse qui marie sols, eau, neige et satellite pour faire de la prévision de catastrophes, et ne baisse pas les bras. Il est toujours plein d'espoir, @greggiuliani.bsky.social.

#ImageOfTheMonth #SwissDataCube | Using #Sentinel-2 and other #Environmental descriptors from #swisstopo we are able to produce a consistent 10m #LandCover map of the entire #Switzerland. This will enable tracking changes in a very detailed way. #EO4impact

Very interesting presentation from Dr. Simon Hook #NASA #JPL on existing and future thermal missions. #ECOSTRES looks particularly interesting #SBSR conference #Salvador #Bahia

After two years, back at #INPE to continue the great collaboration between the Brazil and Swiss Data Cubes on Satellite Image Time-Series #SITS

#ImageOfTheMonth #SwissDataCube | In this Sentinel-2 true color composite, you can see probably the most famous peak of Europe - the #Matterhorn located at border between #Switzerland and #Italy.

#ImageOfTheMonth #SwissDataCube | A recent study in @nature.com has shown that the pace of glacier melting is accelerating: doi.org/10.1038/s415....
The Aletsch Glacier is an icon of the Swiss Alps and its significant decrease in 40 years is a clear consequence of #ClimateChange. #EO4impact

Frontiers | Past and future trends in swiss snow cover: multi-decades analysis using the snow observation from space algorithm

New paper | Using the Snow Observation from Space algorithm and climate projections, we found that snow-free areas in #Switzerland could expand btw 22 to 43% by 2100.

#ImageOfTheMonth with the #SwissDataCube | Prolonged heat and dryness conditions can lead to #drought, serisously affecting lakes like the "Lac des Brenets". This lake experience important water shortages and its level is declining as seen on this #Sentinel2 false color composite. #EO4impact

With the start of the new year, I will try to publish every month a picture of #Switzerland #landscape as seen from space using the #SwissDataCube.
We start with a cloud-free mosaic of the country using all available #Sentinel2 images for 2020. #EO4impact
