Dear friends, I am at the frontlines now. The Russians are likely to initiate a breakthrough in our direction after Avdiivka. Our unit needs two thermal imagers, costing a total of 3,000 euros. I would be grateful if you could help. PayPal: [email protected] Bank: 4149499377721319


My classmate & friend Yan joined the army in Feb 22. His callsign is Mamay after the hero of Ukrainian folklore, and here you can see him next to Mamay mural in Avdiivka. His 53-rd Brigade named after V. Monomakh has been fighting there for one year. They need your help. Donate send.monobank.ua/jar/9bHASWJBAE




Tantilizing new work led by Nikolay Koldunov. It shows that using a well-trained weather forecasting model--which has learned the general dynamics and behaviour of the Earth system!--can make a big difference for a wide range of application, in our case climate downscaling.

Thomas Rackow 🧊 Christian Lessig I really believe this is the way & the 2 approaches have merits: 1️⃣ An IPCC trained downscaling (+bias-correct) using #AI has merits of using a large amount of existing readily available data. 2️⃣ A well trained #AIFS (foundation?) model natively at Km-scale is so cool 😎👍

ArchesWeather will be presented at ICML 2024 In Vienna (ML4ESM Workshop). Big thanks to my collaborators ! Christian Lessig, Anastase Charantonis, Claire Monteleoni



We are coordinating an EU-funded project that aims to use #MachineLearning in novel ways for #WeatherForecasting and related #EarthSystem modelling. Find out more about the aims and methods of the WeatherGenerator project ➡️ ecmwf.int/en/about/media… @C2SM_ETH CSCS Lugano


🌍🌐 Can AI transform climate science? A new preprint paper led by ECMWF and AWI Media tested AI based models in various climate conditions. Results suggest that AI models can skilfully forecast weather in current, past, and future climates! Learn more ➡ destine.ecmwf.int/news/ai-based-…
