Researchers have developed NRFormer+, a novel spatio-temporal Transformer model designed for nationwide nuclear radiation forecasting. This model addresses challenges such as non-stationary time series, uneven spatial distribution of monitoring stations, and the complex interplay between radiation and meteorological factors. NRFormer+ integrates non-stationary temporal attention, density-adaptive spatial attention, and a unique atmospheric diffusion module that incorporates physical signals from meteorology to predict radiation dispersion. The model has demonstrated state-of-the-art accuracy, outperforming 13 baseline models and reducing MAE by up to 19.1%. AI
IMPACT This model could enhance public safety and emergency response by providing more accurate nuclear radiation forecasts.
