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_scl.mat: complete dataset with 10-minute resolution of meteorological and air quality variables for Santiago.

MX50_minmax.mat: complete dataset with 10-minute resolution of VOCs (percentile 50) for Santiago.

Santiago_model.m: model run, use with input_scl.mat, MX50_minmax.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 Santiago_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.
