"Next-Gen Air Quality Model Adapts to Modern Challenges"

The Sulfur Transport and Deposition Model (STEM), developed in 1976, has significantly advanced the understanding of air quality and its interaction with climate. Initially focused on sulfur pollution, STEM has evolved to address a broader range of pollutants and has been instrumental in numerous scientific studies and policy developments. Ongoing updates aim to integrate new meteorological and land surface models, enhance computational capabilities, and support emerging environmental issues, ensuring STEM remains a vital tool for air quality and climate research.
