Files:

1. National model-based chemical regime classifications

"o3data2007.correctedNov2020.csv";  "o3data2016.hddm.csv"
Data files contained measured and modeled MDA8 values as well as daily HDDM sensitivities in each model grid cell. These data sets support the calculation of model based chemical regimes throughout the paper.

"tmp.trim.2007.rdata"; "tmp.trim.2016.rdata"
Data files ozone chemical regime classifications assigned based on calculated ozone deltas according to modeled HDDM sensitivities following the approach documented in the methods. These data sets support the visualization of model-based chemical regimes throughout the paper.

"create_annual_gridded_cat_plots.2007.2016.national.r"
Script used to create national maps of model-based ozone chemical regime classifcations.

2. DOW analysis   

"o3dow.04dec2020.rdata"
Archive R data file that contains modeled and observed values used in the DOW calculations throughout the paper

"o3data.r"
Script used to produce boxplots from DOW analysis.

3. Ozone isopleths

"Ozone.csv"; "responsiveness.csv"; "required_reductions_allnox_or_allvoc_2007.csv"; "required_reductions_allnox_or_allvoc_2016.csv" 
Data files containing HDDM sensitivities used to calculate ozone isopleths

"EKMA.ipynb"
Script used to create ozone isopleth plots for specific locations.
