Abstract

Source code and dependent datasets used to model the perturbations to tropospheric ozone (O₃) and methane (CH₄) due to South Korean air pollution emissions. The modelling system consists of three stages: The boundary layer-residual (BL-RL) stage (BL-RL), plume (PL) stage, and dispersed pollution (DP) stage. The directory contains a modified version of F0AM v3.1, Emission inventories (KORUS v5, GFED5, and MEGAN v2.10), and processed datasets from ERA5, EDGAR, KORUS-AQ, and ATom.

Access this dataset on Dryad

A three-part modelling system of South Korean air pollution in the boundary layer and residual layer (BL-RL stage), transported offshore as pollution plumes (PL stage), and as dispersed perturbations to the background air (DP stage). Modelling_System.zip contains the source code run the modelling stages, and output from those runs, documented at [https://doi.org/10.5194/egusphere-2025-6012]. Running the model stages requires MATLAB (e.g. R2022A) and some datasets from the complementary Zenodo repository (F0AM_and_Inventories.zip). Extract the directories within F0AM_and_Inventories.zip to Modelling_System/Data/ before attempting to run the model components (e.g., Modelling_System/Data/KORUSV5)

Description of the data and file structure

Additional README.md files are provided inside the model base directory and subdirectories. The basic directory structure is as follows:

Source/

Source code for running the model stages.

Output/

Location for saved output subdirectories generated by the BLRL model. Output subdirectories are used as input to the PL model and analysis tools.

Data/

Datasets used by the modelling system including ERA5, emissions inventories (KORUS-v5, GFED5, MEGAN v2.10, and EDGAR temporal scalings), chemical mechanisms from MCM v3.1.1 (Chem/ subdirectory), and observational datasets. Some of these datasets must be downloaded and extracted here from the complementary Zenodo repository (F0AM_and_Inventories.zip).

Analysis/

Tools for analysing the output subdirectory data. Scripts in this directory contain example input.
