On my way to #LPS25 and looking forward to one week of condensed #earthobservation! Our team will present a broad portfolio of tree species unmixing, sea ice, land surface phenology, and human-made material mapping. Also come and chat with me during the open science in the making session - #FORCE_EO

📣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‼️

I'm so happy and proud of this decision 🙂. It is very important now to use the data, and compare the performances obtained with 2 and 3 satellites in your future communications. It will be the good way to thank @esa.int and #Copernicus.
Some more good news for the Sentinel-2 mission!
Sentinel-2A, which recently retired, has been given a temporary extension, where it will support S2B and S2C to provide additional data.
Lots of hard work behind the scenes to make this happen. Glad to see it!
