Investigating Ground-Level Ozone Pollution in Semi-Arid and Arid Regions of Arizona Using WRF-Chem v4.4 Modeling Y. Guo https://doi.org/10.5281/zenodo.10479471

Short summary

This research focuses on surface ozone (O₃) pollution in Arizona, a historically air-quality-challenged arid and semi-arid region in the US. The unique characteristics of this kind of region, e.g., intense heat, minimal moisture, and persistent desert shrubs, play a vital role in comprehending O₃ exceedances. Using the WRF-Chem model, we analyzed O₃ levels in the pre-monsoon month, revealing the model's skill in capturing diurnal and MDA8 O₃ levels.
