AI weather model Aardvark adds uncertainty quantification

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a probabilistic version of the Aardvark Weather model, an end-to-end AI system for weather forecasting. This enhancement addresses the deterministic nature of previous models by incorporating stochastic mechanisms to capture both aleatoric uncertainty from observations and epistemic uncertainty from the learned dynamics. The resulting nested ensemble attributes forecast spread to these two sources, improving mean forecasts by 4.2% and demonstrating calibration against ERA5 data. This approach offers greater transparency by making forecasts observation-driven, a step towards creating digital twins of the atmosphere. AI

IMPACT Enhances AI weather models with uncertainty quantification, improving transparency and reliability for atmospheric digital twins.
