Aviation NOx Impact on Ozone Radiative Forcing from EMAC Model Simulations

Pratik Rao from Delft University of Technology provides a post-processed dataset accompanying a journal article under review. The data originates from simulations with the ECHAM/MESSy Atmospheric Chemistry model (EMAC) and estimates the short-term impact of aircraft nitrogen oxide emissions on atmospheric ozone. It includes results for five global regions, three pressure altitudes, and two seasons, calculated using Eulerian tagging, Lagrangian tagging, and perturbation methods.

Use Cases

• Estimating regional ozone radiative forcing from aviation NOx based on the described Lagrangian tagging method.
• Comparing atmospheric chemistry model outputs across different calculation methods (Eulerian tagging, Lagrangian tagging, perturbation).
• Analyzing seasonal and altitudinal variations in ozone impact from aircraft emissions for the specified regions.
• Validating probabilistic approaches for calculating radiative forcing using the provided emission point data.

Strengths

• Data is derived from the ECHAM/MESSy Atmospheric Chemistry model (EMAC), a recognized atmospheric simulation tool.
• Covers five distinct geographical regions (North America, Eurasia, South America, Africa, Australasia) and two seasons.
• Includes results from three different calculation methodologies for comparative analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
