🔚 Fin du #CALIPSO Symposium sur les lidars spatiaux ! Cet événement a mis en lumière la valeur des lidars spatiaux et leur synergie avec d'autres observations pour comprendre climat, météo et qualité de l'air. #ICESAT #AEOLUS #EarthCare 🚀

I am very happy to announce DeltaDTM, a cutting-edge global coastal Digital Terrain Model (DTM) made by @deltares which was just published in Nature Scientific Data https://www.nature.com/articles/s41597-024-03091-9. Other coastal elevation models are often based on older data, or commercial in nature. DeltaDTM is the most accurate thus far, and free for everyone (CC-BY licensed). This publication is the first paper of my PhD research on creating better global elevation models using #NASA #ICESat-2 and #GEDI data.

Check out our newly published paper about sea ice–atmosphere drag coefficients from #ICESat-2 laser altimeter topography data, the first monthly pan-Arctic assessment of its kind. #AC3TR @CRiceS_H2020 ➡️ https://tc.copernicus.org/articles/17/4103/2023/

The National Astronomical Observatory of Japan has said that NASA believes the bright green lasers were likely from a Chinese satellite.

Evidence of #phytoplankton blooms under #Antarctic sea ice: https://www.frontiersin.org/articles/10.3389/fmars.2022.942799/full (using #ICESat-2 data) -> Phytoplankton May Be Abundant Under Antarctic Sea Ice, Study Suggests: https://www.nasa.gov/feature/esnt/2022/phytoplankton-may-be-abundant-under-antarctic-sea-ice-study-suggests

#ICESat-2 does more than measure polar ice. It also makes detailed observations of elevation in tropical and temperate latitudes. This is what the #satellite observed as it passed over a forested hillside in #Mexico. https://earthobservatory.nasa.gov/images/144450/icesat-2-sees-the-trees-in-mexico #NASA
