🌬️ Can ML forecasts follow the laws of physics?
PACE checks if models like GraphCast & CorrDiff stay consistent over time + space.
Part of #CodeForEarth 2025 — because forecasts shouldn’t fake it.
#ClimateTech #PhysicsAwareAI #CodingPhase
🔍 Model behaving badly?
EVALKIT is your open-source toolkit for forecast error detection — with interactive notebooks, Earthkit, and sharp diagnostics.
Part of #CodeForEarth 2025, built for data detectives.
#ClimateTech #WeatherModels #CodingPhase
🔥 Meet Fire Front Radar – a real-time, interactive web app for exploring fire-related data across the globe.
Part of #CodeForEarth 2025, it's built to keep up with the speed of wildfires — and help you see the heat coming.
#ClimateTech #WildfireData #CodingPhase
🖼️ Visualising CAMS data just got way easier.
This #CodeForEarth 2025 project brings interactive air quality forecasts to your browser — no tools, no downloads, just click & explore.
From sandstorms to methane leaks, it's climate data made visible.
#ClimateTech #AirQuality #CodingPhase
⚙️ Meet MLCosting, a smart ML-based plug-in for predicting DSS request costs at ECMWF.
Trained on real data, it estimates execution time, dataset size & classifies load.
Part of #CodeForEarth 2025.
#ClimateTech #MachineLearning #APItools #CodingPhase
🧠 Meet EarthReach Agent, a dual-LLM system making meteorological charts accessible to visually impaired scientists.
One LLM writes expert-level descriptions, the other checks their accuracy.
