#Sentinel-2A 🛰️ contributed on average 𝟮𝟬% of cloud-, shade-, and snow-free acquisitions to the Sentinel-2's data pool between March 2025-2026! 📣 Check out our paper doi.org/10.1016/j.rs... for more details! with @hagolleo.bsky.social @hostertp.bsky.social #Copernicus #EarthObservation @esa.int

📣Our global 🌍 overview of usable (cloud-, shade, and snow-free) #Landsat and #Sentinel-2 🛰️ data is now supporting 1982-2025! You can browse the data via a #GEE app: tinyurl.com/322e63p2 and download it for more in-depth analysis doi.org/10.5061/drya...

Dear @eea.europa.eu @copernicusland.bsky.social what happened to the HRL for grasslands and forest reference years: 2006, 2009, 2012? Only imperviousness datasets are still being mention on the websites and available for download. The old HRL were and are treasure trove for pre-Sentinel-2 times!

🌍 After excluding clouds, shade and snow, how much #Sentinel-2 and #Landsat 🛰️ do we really have for 2025?! Continuing our mission and previous research (tinyurl.com/2kbwesbj), we added 2025 to our #GEE App tinyurl.com/322e63p2. Take advantage of this data when planning your #RemoteSensing analysis

`All governments suffer a recurring problem: Power attracts pathological personalities.` F.H. I hope we live to see a day when all war criminals, from ordinary soldiers to national leaders, are held accountable, regardless of country.

in the recent weeks Europe started to move towards data and technology sovereignty. But we have one huge blind spot: Two the most popular mobile OS are owned by US Big Tech, and Google is quietly tightening the noose on Android.

The World burns, yet the Olympics roll on, with many participating countries violating international conventions and basic human rights daily. but the show must go on, because when capitalism rules, accountability is out-of-fashion. panem et circenses

🏴‍☠️ 'more than 250 million acres of public lands will be eligible to be sold to "any interested party."' Another !brilliant idea to fund agenda of the current US administration. www.wilderness.org/articles/blo...

wilderness.org

Congress is making more than 250 million acres of public lands available for sale.

The Senate reconciliation package is a disturbing giveaway that will mandate the “disposal” of public lands across the western United States.

There are 2 previous historical cases of countries destroying their science and universities, crippling them for decades: Lysenkoism in the USSR and Nazi Germany. The Trump administration will be the 3rd. It's not just budgets but research, institutions, expertise, and training the next generation.

Graphs showing 25 years of budgets for the National Institute of Health, NASA, and the NSF. In all cases, the proposed budget for next year is far, far below any year of the previous quarter century.

A daunting document outlining, among others, the future of the #Landsat program. Only a bunch of troglodytes could call the Landsat Next 'unaffordable', especially when its budget is like a drop comparing to the US military expenses. www.nasa.gov/wp-content/u...

In @nytopinion.nytimes.com Three Yale professors who have written extensively on authoritarianism are leaving the U.S. “We’re like people on the Titanic saying our ship can’t sink,” Marci Shore said. “And what you know as a historian is that there is no such thing as a ship that can’t sink.”

Opinion | We Study Fascism at Yale. We’re Leaving the U.S.

The decision by these three Yale professors to move to Canada is both a warning and a call to action.
