Combining #EarthSystemModels with river data from 50 basins, allowed for refined global #WaterCycle estimates: river flow and flow-to-precipitation ratios are lower than thought, #GlobalWarming may raise flow by ~7.8 mm/yr per °C.

🌍 Meet the #EarthSystemModels powering our project!
Over the next weeks we’ll share 5 unique #ESMs — what makes them special, the science they enable, & how we’ll advance them.
🚀 ICON-ESM, UKESM, EC-EARTH, CNRM-ESM, IPSL-CM.
#ClimateModeling #AI4Climate
🚀 First GA for #AI4PEX in Lund!
Last month partners from across Europe met to advance #EarthSystemModels with #AI, #ML & #EarthObservation - tackling ✨ Benchmarking 🛠 Syncing milestones 🌍 Boosting outreach 🤝 Hands-on collaboration.
Big thanks to Lund University for hosting!

🚀 Day 1 of the OptimESM General Assembly is underway! 🚀
We’ve officially kicked off the OptimESM General Assembly that take place in Postdam and online. Looking forward to a productive few days of collaboration and idea-sharing!

💡 New Paper!
#MachineLearning improves #EarthSystemModels, but explaining its added value is tough. Inspired by climate model hierarchies, we propose using Pareto-optimal models to distill ML's added value in representing cloud cover, radiative transfer and tropical precipitation.

📡This week #CONCERTO_WorkPackages presents you WP3, which focuses on enhancing #satellite-based vegetation data assimilation to improve #climate modelling.
🌍Led by @ecmwf.int this work package is developing advanced multivariate land data assimilation #techniques for #EarthSystemModels.
What are the climate models we are working on? Land model number 3:
ORCHIDEE (Organising Carbon and Hydrology In Dynamic Ecosystems), the land surface model of the IPSL #EarthSystemModels, where our focus is especially on the hydrological processes.

🚀Starting this week, we’re launching #CONCERTO_WorkPackages, a campaign showing all 8 Work Packages of CONCERTO.
Each Work Package helps to improve the Earth System Models & reduce uncertainties in #carboncycle predictions.🌍🌱
📣Follow us for more interesting insights on #EarthSystemModels!
📣 Digital Earths lighthouse activity is organizing a global pan-hackathon for km-scale models! Dozens of researchers from across the world will participate in this hackathon in real-time.
Here is a curtain-raiser video about the event: loom.ly/xYErXdU
#KmScalemodels #EarthSystemModels #Hackathon
#OptimESM will provide progress in 5 key areas: next generation of high-resolution #EarthSystemModels; ii) new policy-relevant emission and land-use scenarios; iii) better uncertainty estimations; iv) #abruptclimatechange; v) regional consequences of global #climatechange. (6/6)
#OptimESM will use,develop and improve the most advanced existing #EarthSystemModels to provide new #futureclimate simulations for a range of new emission scenarios produced by the project's #IntegratedAssessmentModels. (5/6)
WE ARE LIVE at Bluesky! SMHI is the proud coordinator of
@horizoneu.bsky.social project #OptimESM! #OptimESM will develop the next generation of #EarthSystemModels to deliver improved climate projections in support of policy and societal needs. (1/6)

#AI4PEX research focus 6: Uncertainty Quantification
To overcome limitations of traditional manual calibration methods, such as high computational costs and slow iterative processes, we improve uncertainty quantification by leveraging on Perturbed Parameter Ensemble.

📍Ice sheets have a much longer memory of the initial conditions than the rest of the climate system
👉How to initialise #EarthSystemModels which include interactive ice sheets?
👉How did real 1850 pre-industrial ice sheets look like?
(5/6)
It's scientifically clear that if we're to model what is going to happen with ice sheets in the coming centuries & if we want to reduce the uncertainty of low-likelihood high-impact sea-level rise projections, it's crucial to include ice sheet dynamics in #EarthSystemModels

#AI4PEX research focus 2: Model Development
To develop better #EarthSystemModels we will expand the use of #EarthObservation in combination with #MachineLearning. We focus on explainability of #AI models and causality to better identify model-observations mismatch.
#AI4PEX research focus 1: #EarthObservation
We leverage existing in-situ observations and EO data-streams to generate new upscaled #MachineLearning -based products, and cross-check with the Copernicus land, ocean and atmospheric datasets.
#EarthSystemModels #climatescience
