Short summary
Atmospheric models struggle to accurately map suspended particles at different altitudes. We developed an artificial intelligence tool using multiple data sources to correct these errors, generating precise three-dimensional maps. This approach successfully reduces biases across Asia and North America. Beyond simply correcting data, our tool helps scientists pinpoint physical flaws in existing models, directly guiding improvements for future climate and air quality research.
