Premise: In this analysis, we used two of these well-established models, the Regional Modeling System for Aerosols and Deposition (REMSAD) and the Comprehensive Air Quality Model with Extensions (CAMx), to develop a picture of future changes in air quality resulting from the implementation of the Clear Skies Act.

Hypothesis: We used the Air and Train Systemic Model(ATSM) to create the entirety of this picture.
Relation: contradiction
