Help Shape iCESM: User Survey
We’re developing the next-generation isotope-enabled Community Earth System Model (iCESM) with water isotope and tracking capabilities.
Please help guide development and documentation by completing the iCESM User Survey (~10 minutes): forms.gle/gBftvVGEQeMW...

A high-resolution simulation illustrating ocean currents with vibrant colors. The warm currents are depicted in red and orange, centrally concentrated along the equator, while cooler currents appear in blue and green. Continents, including North America, South America, Africa, Eurasia, and Australia, are visible.
We’ve got a new dataset that’s hi-res and research ready: MESACLIP. Researchers used two supercomputers to create the MESACLIP dataset which features the Earth system in unprecedented detail, including snow cover and sea surface temperatures. Learn more: https://bit.ly/4rBK9bg

The BAMS State of the Climate report shares the latest, reliable measurements of Earth’s system, with input from 590 scientists across 58 countries. Explore many of the datasets on the CGD Climate Data Guide. 🔗 lnkd.in/gvgP2Ryx
🌊 NSF NCAR hosted the first CROCODILE & MOM6 Workshop at the Mesa Lab in Boulder, bringing together 30 scientists for a week of collaboration and hands-on modeling. 🌎 Teams are developing tools to build regional ocean models in hours, not weeks. Watch recordings: lnkd.in/gmibERzU
Thrilled to see two of my mentors Dr. Bette Otto-Bliesner (Suki Manabe Award) and Prof. Zhengyu Liu (Sverdrup Gold Medal) honored by @ametsoc.org for their pioneering work on Earth’s climate system through modeling and paleoclimate research. @ncar-ucar.bsky.social @ncar-cgd.bsky.social
🎉🎉 CONGRATULATIONS to Dave Lawrence @ncar-ucar.bsky.social @ncar-cgd.bsky.social for being honored as a 2025 @agu.org Fellow! 🎉🎉
Dave is a CESM Chief Scientist at NSF NCAR, and serves as LEAP's NCAR Model Development Liaison. Well done + well-deserved, Dave!
🌊 In 2012, CGD’s Aixue Hu showed how closing the Bering Strait in models affects Atlantic currents. Today, Science revisits this idea, asking if a giant dam could help keep Europe warm. Why it matters: ocean gateways, tipping points & bold ideas all collide. 🔗 lnkd.in/gS_sHikw
🌍💧 New models reveal the secret life of water!
SCI-SWIM, led by Rice & NCAR with NSF support, tracks where rain comes from using stable water isotopes — tracing moisture from oceans to clouds to ice sheets.

We recently conducted a week-long training for our 3D-Printed Automatic Weather Stations (3D-PAWS) at the Red Lake Nation College. We trained staff to fabricate two 3D-PAWS systems for educational and research studies on the Red Lake Tribal Lands. We're excited for this partnership!
In 2024, U of Idaho got a 6-year NSF grant to study how drought & wildfire affect western forests. EMBER unites scientists incl. CGD’s Will Wieder. He joined the EMBER Boot Camp in May to explore forest recovery. 🌲🔥🌎 lnkd.in/gyMBWevw #ForestResilience #WildfireScience
To determine how much the gusts have weakened, the research team put on their detective hats, analyzing measurements from different wind instruments that have been moved and replaced over the years.

What has @ncar-ucar.bsky.social done for you? A public tour of the Mesa Lab is a great way to get to know our impact. Our research has been protecting lives and property across the United States since the 1960s, and we'd love to tell you about it!
