This dataset contains outputs from WRF-Chem version 3.7 and a jupyter notebook (Python 3.0) script that were used to generate the figures included in the manuscript. Each numpy file contains data from July 1, 2012 00:00 LST - July 31, 2012 23:00 LST. Dataset contents and naming conventions are described below. The directory called "pubFigs" contains two jupyter notebooks that generate the figures referenced in the main text (Final_Figures.ipynb) and supplementary information (Final_SI_Figs.ipynb). Figures are generated using processed WRF output data for each of the simulations described in the manuscript. Files that end with "2012runbc.npy" correspond to the Baseline simulation Files ending with "GVF.npy" correspond to the GVF50 simulation Files ending with "BVOC_Low", "BVOC_Med", and "BVOC_High" correspond to the low, medium, and high BVOC emissions scenarios Files ending with "LA100" used the future anthropogenic emissions scenario Files that do not end with "LA100" used the current day anthropogenic emissions scenario An additional file called "Pouya_LU.npy" contains the land cover/ land use codes from our model configuration and is used to plot diurnal cycles of urban and nonurban land cover.
