📣In our new paper we analyzed the impact of #Landsat and #Sentinel-2 🛰️ #satellite data density and SMA endmembers on trends in #grasslands ground cover:
- for monthly composites data density is irrelevant
- correct endmember definitions are critical‼️

that is also a possibility. However, in my very naive take on it: the Starlink hardware is already deployed on the ground and a change would generate massive costs and need to adjust established workflows and software connections, which could jeopardize the military operation.

with all the respect, but it is not true. Starlink is probably the most well known provider of such services, but there are many alternatives, some 100% european.

looking forward especially to your take on #1!
From the environmental point of view it is a good thing that we, as a species, will reduce in numbers. The only thing that suffers is capitalism that assumes infinite growth and resources🙄

We keep growing!
Are you excited about remote sensing and mountain forests? Then consider applying to this PhD position, supported by the TUM Center for Forest Management in the Alps! More details at: portal.mytum.de/jobs/wissens...

i mean, why to limit oneself to experts? we should extend out lack of trust to politicians or, even better, all the people, since anyone who could be an expert in something.
Most of all, we should not trust that people in power have good intentions.

A kind reminder to all @esa.int's #LPS25 attendees that today during the 𝐂.𝟎𝟓.𝟎𝟒 session at 𝟏𝟔:𝟏𝟓-𝟏𝟕:𝟒𝟓 (𝐇𝐚𝐥𝐥 𝐋𝟏/𝐋𝟐) I will present on the global availability of usable Landsat and Sentinel-2 data and how it impacts feasibility of analyses.
Hope to see many of you in the audience!

If you are interested in scaling up your #remote_sensing analyses but do not know how, come for the inspiration to the @esa.int's #LPS25 session 𝗗.𝟬𝟰.𝟬𝟱 (𝗧𝗵𝗿 𝟮𝟲𝘁𝗵 𝗝𝘂𝗻 | 𝟴:𝟯𝟬-𝟭𝟭:𝟬𝟬 | 𝗛𝗮𝗹𝗹 𝗟𝟯) led by @kristofvantricht.bsky.social, @marccoru.bsky.social and me.

📣Attending @esa.int's #LPS25 next week?
Make sure to catch the 𝐂.𝟎𝟓.𝟎𝟒 session (𝐓𝐮𝐞 𝟐𝟒𝐭𝐡 | 𝟏𝟔:𝟏𝟓-𝟏𝟕:𝟒𝟓 | 𝐇𝐚𝐥𝐥 𝐋𝟏/𝐋𝟐), during which I will talk about 🌍 global 🛰️ #Landsat and #Sentinel-2 data availability and how it shapes feasibility of long-term analyses.
See you in Vienna!

To celebrate the #ShowYourStripes Day a few places (or their approximations) i called home over the past years. (Sorry Madison WI, but you are not supported in the app :|)

it is scary... 🥵

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.

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.”

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

With all the talk about #AI taking our jobs - i think we are fine for now. #Google's #Gemini will arrive to work on a wrong day of the week 😅

The EU flag has one major drawback—or feature: when flown upside down, it looks exactly the same as when flown correctly. 😅

i could not agree more! The level of darkness and messages through Anathema's albums changes so much. Fantastic music and deeply meaningful lyrics.
'Lost Control' through 'A Fine Day to Exit' to 'Dreaming Light'. What a trip and the life soundtrack
