Researchers have introduced PiCo, a novel framework designed to probe the physical sensitivities of Geo-Foundation Models (GFMs). Unlike traditional evaluations that focus solely on downstream task performance, PiCo aims to reveal which physical features these models utilize in their predictions. By generating synthetic satellite observations from a 3D radiative transfer model and a game engine, PiCo identifies concept vectors within the model's embedding space. These vectors allow for the quantification of concept importance in predictions and facilitate hypothesis testing about model behavior, particularly in Earth observation tasks. AI
