Large atmospheric base model

Microsoft released Aurora, the first large-scale atmospheric base model for weather prediction on Monday, which enables high-precision forecasts of weather and atmospheric changes. Aurora is a 1.3 billion parameter base model for high-resolution forecasts of weather and atmospheric processes. Aurora is a flexible 3D Swin Transformer with a 3D perceptron-based encoder and decoder. During pre-training, Aurora is optimized to minimize the loss of multiple heterogeneous datasets with different resolutions, variables, and pressure levels. Then it is divided into two…
