Microsoft has developed Aurora, an artificial intelligence (AI) model capable of accurately predicting global weather and air pollution conditions in less than a minute.
Aurora is part of a series of AI weather forecasting tools being developed by leading tech companies, such as Google DeepMind's GraphCast and Nvidia's FourCastNet. However, Aurora stands out due to its groundbreaking ability to quickly forecast global air pollution.
In less than a minute, Aurora can predict levels of six major air pollutants worldwide, including carbon monoxide, nitrogen oxides, nitrogen dioxide, sulfur dioxide, ozone, and particulate matter. It offers a five-day prediction span and achieves this with a reduced computational cost compared to traditional models.
To train Aurora, researchers utilized over 1 million hours of data from six weather and climate models. After training the model, the team fine-tuned it to predict both pollution and weather patterns across the globe. Consequently, Aurora generates a 10-day global weather forecast while simultaneously making air pollution predictions.
