摘要 | The purpose of this study is to evaluate the ozone (O-3) formation along the California Mexico border region using the WRF-CHEM model in association with the Cal-Mex 2010 field campaign. Four two-day episodes in 2010 are chosen based on plume transport patterns: 1) May 15-16 (plume north), 2) May 29-30 (plume southwest), 3) June 4-5 (plume east), and 4) June 13-14 (plume southeast). Generally, the predicted O-3 spatial patterns and temporal variations agree well with the observations at the ambient monitoring sites in the San Diego-Tijuana region, but in the Calexico-Mexicali region, the model frequently underestimates the observation. In the San Diego-Tijuana region, the morning anthropogenic precursor emissions in the urbanized coastal plain are carried inland and mixed with the local biogenic emissions during transport, causing the high O-3 level over the mountain region. Biogenic emissions enhance the O-3 concentrations by up to 40 ppb over the mountain region in the afternoon. The factor separation approach is used to evaluate the contributions of trans-boundary transport of emissions from California and Baja California to the O-3 level in the California Mexico border region. The Baja California emissions play a minor role in the O-3 formation in the San Diego region and do not seem to contribute to the O-3 exceedances in the region, but have large potential to cause O-3 exceedances in the Calexico region. The California emissions can considerably enhance the O-3 level in the Tijuana region. Generally, the California emissions play a more important role than the Baja California emissions on O-3 formation in the border region (within 40 km to the California Mexico border). On average, the O-3 concentrations in the border region are decreased by 2-4 ppb in the afternoon due to the interactions of emissions from California and Baja California. Further studies need to be conducted to improve the sea breeze simulations in the border region for evaluating O-3 formation. |
