TianJi-Environ: An Autonomous AI Scientist for Atmospheric Environmental Research
TLDR
TianJi-Environ is an autonomous AI scientist using multi-agent WRF-Chem simulations to validate atmospheric chemistry mechanisms with real-world case studies.
Reasoning
The paper presents a novel multi-agent framework for automated mechanism validation in atmospheric chemistry, demonstrated with real-world ozone and PM2.5 cases. However, it is domain-specific and lacks comparison to human expert performance or generalizability claims.

Innovations
- First WRF-Chem-based multi-agent framework for autonomous atmospheric-chemistry mechanism validation
- Converts mechanistic hypotheses into executable configurations, testing experiments, and evidence criteria
- Auditable AI Scientist that makes expert-driven mechanism validation explicit, structured, and reproducible
Methodology
TianJi-Environ is a multi-agent system coupled with the WRF-Chem model that autonomously translates mechanistic hypotheses into simulation experiments, executes them, and evaluates outputs against predefined evidence criteria. It is demonstrated on two case studies: summertime ozone over the North China Plain and wintertime PM2.5 over the Guanzhong Basin.
Key Results
In the ozone case, the system detected aerosol-radiation-interaction signals but judged evidence for ozone response to NOx control incomplete. In the PM2.5 case, it localized the unsupported link to insufficient propagation from black-carbon perturbation to particulate response and missing diagnostics of vertical absorptive heating.
