Researchers have developed a new method to evaluate self-supervised learning (SSL) representations in geospatial data by probing them with environmental signals. This approach uses co-located ERA5 reanalysis variables, such as temperature and precipitation, to assess how well SSL models like DINO, MAE, and MoCo encode information relevant to environmental conditions. The study found that representation-level metrics can differentiate models with similar downstream task performance and that the accessibility of environmental signals correlates with performance on environmentally dependent tasks.
