Description

These files have been prepared for the paper entitled "Comparative ozone production sensitivity to NOx and VOCs in Quito, Ecuador and Santiago, Chile" submitted to Atmospheric Chemistry and Physics in March, 2025. Authors: María Cazorla1, Melissa Trujillo1, Rodrigo Seguel2,3, Laura Gallardo2,3 1Universidad San Francisco de Quito USFQ, Instituto de Investigaciones Atmosféricas, Quito, Ecuador 2Center for Climate and Resilience Research (CR2), Universidad de Chile, Santiago, Chile 3Departamento de Geofísica, Facultad de Ciencias Físicas y Matemáticas, Universidad de Chile, Santiago, Chile This dataset belongs to a comparative analysis of ozone production rates in Quito, Ecuador and Santiago, Chile. Preprint available at: https://doi.org/10.5194/egusphere-2024-3720 Here we provide the MATLAB code and files used to run the model. Additionally, files can be found in the path: Photochemical_Model_Quito_Santiago>Quito Input Files F0AM, at https://observaciones-iia.usfq.edu.ec/ Files input_uio.mat: complete dataset with 10-minute resolution of meteorological and air quality variables for Quito. MX50_UIO.mat: complete dataset with 10-minute resolution of VOCs (percentile 50) for Quito. Quito_model.m: model run, use with input_uio.mat, MX50_UIO.mat, and mcm_subset.m. This is an executable file for the F0AM (Framework for 0-D Atmospheric Modeling) (Wolfe et al., 2016). mcm_subset.m: MCMv331 mechanism with all the chemical species used. This mechanism is called in Quito_model.m. The chemical mechanistic information was taken from the Master Chemical Mechanism, MCM v3.3.1 (Bloss et al., 2005; Jenkin et al., 1997, 2003, 2015; Saunders et al., 2003), via website: www.mcm.york.ac.uk.

Files

Steps to reproduce

For running the model download all files and run Quito_model.m with MATLAB. The model calls for mcm_subset.m. The name of the output file can be changed in ModelOptions.SavePath, inside the model.
