ADMS-Screen 3.1

ADMS-Screen is a screening-level air dispersion modeling tool used to estimate conservative, worst‑case ground-level pollutant concentrations from simple emission sources, typically a single stack or vent. It is designed for rapid, early-stage assessments—such as permit pre‑screening, odour checks, or preliminary health risk reviews—so users can quickly determine whether more detailed modeling is required.

By combining straightforward inputs (e.g., emission rate, stack height, exit temperature, and velocity) with built-in worst‑case meteorological assumptions, ADMS-Screen produces quick, precautionary concentration estimates and indicates the distance to maximum impact. Results help planners, consultants, and facility operators prioritize mitigation steps and decide when to move to a full-featured dispersion model.

Key points:

• Purpose: fast, conservative screening of air quality impacts from simple sources
• Typical inputs: emission rate and basic stack parameters
• Typical outputs: maximum ground-level concentration and distance to maximum, concentration profiles with simple averaging times
• Use cases: early-stage regulatory screening, odour assessments, feasibility studies
• Benefits: quick to set up and run, supports decision-making before detailed modeling
• Limitations: not intended for complex scenarios (multiple sources, detailed chemistry, complex terrain); a full dispersion model is recommended when higher fidelity is needed
