Israel's Meteorological Service Predicts the Weather Using NVIDIA Earth-2
Israel Meteorological Service (IMS)· IsraelNVIDIA Earth-2 · NVIDIA PhysicsNeMo · CorrDiff
The Israel Meteorological Service integrated an AI weather model called F3, powered by NVIDIA Earth-2 and NVIDIA PhysicsNeMo (including the CorrDiff neural network), into its forecasting system to achieve hyperlocal 2.5-kilometer resolution precipitation forecasts. F3 achieved 90 percent lower computational costs compared to running a classic non-AI numerical weather prediction model on a CPU cluster, delivering forecasts in minutes rather than hours, and saved 20-30 percent of the Tel Aviv-Yafo Municipality's preparedness budget for things like urban flood safety. CorrDiff was trained to emulate IMS's regional high-resolution ICON model using low-resolution ECMWF IFS input, enabling four high-resolution forecasts per day. Partners including the Israeli Police, the National Fire and Rescue Authority, the Ministry of Transportation and the National Road Company have adopted the forecasts, and IMS used F3 to issue a high-resolution flood map during a January storm that dropped 150 millimeters of rain in six hours.

Inspect the highlighted sourceThe challenge
IMS is located in a Mediterranean climate zone with diverse weather patterns, from intense flooding to fire seasons; as the climate continues to change, predicting the weather is becoming increasingly difficult. Traditional, non-AI weather models typically take hours to run using large supercomputing clusters and require a huge amount of compute time to generate predictions.
The solution
IMS integrated an AI weather model called F3, powered by NVIDIA Earth-2 and NVIDIA PhysicsNeMo (including the CorrDiff Corrector Diffusion neural network), into its forecasting system. CorrDiff was trained to emulate IMS's regional high-resolution ICON model using low-resolution ECMWF IFS input, enabling four high-resolution forecasts per day at hyperlocal 2.5-kilometer resolution. With Earth-2's open source software and open science models, IMS built a full stack across hardware and software that it runs as a sovereign capability.
Reported business value
F3 achieved 90 percent lower computational costs compared to running a classic non-AI numerical weather prediction model on a CPU cluster, delivering forecasts in minutes rather than hours, and saved 20-30 percent of the Tel Aviv-Yafo Municipality's preparedness budget for things like urban flood safety. Partners including the Israeli Police, the National Fire and Rescue Authority, the Ministry of Transportation and the National Road Company have adopted the forecasts. IMS used F3 to issue a high-resolution flood map during a January storm that dropped 150 millimeters of rain in six hours, giving government agencies the ability to shut down roads and avoid casualties.

Austrian Academy of Sciences unlocks Ancient Greek with Mistral
The Austrian Academy of Sciences (OeAW), together with its Austrian Archaeological Institute, partnered with Mistral and services partner Reply to build Apollo, described as the first advanced large language model for Ancient Greek. Apollo is trained on a specialized corpus of 600 million words of historical Greek text plus tens of thousands of published inscriptions and papyri, helping researchers reconstruct damaged texts and identify thematic connections across collections. The OeAW reports Apollo turns work that once took years into hours, addressing over one million unread Greek papyri worldwide, with future phases planned for semantic search and handwritten inscription decipherment.
