近几十年来，由于气候变化和森林管理实践的影响，美国西部的野火频率有所增加。因此，由于野火，人类结构，健康和生命越来越受到威胁。此外，野火烟雾对区域和国家空气质量的危害越来越大。作为回应，人们开发了许多科学工具来研究和预测野火行为，或测试可能减轻风险的干预措施。在这项研究中，我们对2020年北方加州野火季节的1个月进行了回顾性分析，当时许多具有不同环境和行为的野火影响了区域空气质量。我们模拟了这一时期使用耦合数值天气预报模型与在线大气化学，并比较两种方法来表示烟雾排放：一个在线火灾蔓延模型驱动的遥感火灾到达时间和生物质燃烧排放清单。首先，我们量化了烟雾排放和火灾活动时间的差异，并描述了随后对烟雾排放估计的影响。接下来，我们将模拟烟雾与地面观测和遥感烟雾进行比较;我们发现，尽管模拟烟雾表面浓度存在差异，但这两种模型的准确度相似。我们对这两种方法的性能和相对优势进行了详细比较，并讨论了可以进一步改进未来野火烟雾模拟的潜在改进。最后，我们描述了烟雾和气象之间的相互作用在这一事件中，并讨论了区域烟雾的增加可能对未来的气象条件的影响。
Wildfire frequency has increased in the Western US over recent decades, driven by climate change and a legacy of forest management practices. Consequently, human structures, health, and life are increasingly at risk due to wildfires. Furthermore, wildfire smoke presents a growing hazard for regional and national air quality. In response, many scientific tools have been developed to study and forecast wildfire behavior, or test interventions that may mitigate risk. In this study, we present a retrospective analysis of 1 month of the 2020 Northern California wildfire season, when many wildfires with varying environments and behavior impacted regional air quality. We simulated this period using a coupled numerical weather prediction model with online atmospheric chemistry, and compare two approaches to representing smoke emissions: an online fire spread model driven by remotely sensed fire arrival times and a biomass burning emissions inventory. First, we quantify the differences in smoke emissions and timing of fire activity, and characterize the subsequent impact on estimates of smoke emissions. Next, we compare the simulated smoke to surface observations and remotely sensed smoke; we find that despite differences in the simulated smoke surface concentrations, the two models achieve similar levels of accuracy. We present a detailed comparison between the performance and relative strengths of both approaches, and discuss potential refinements that could further improve future simulations of wildfire smoke. Finally, we characterize the interactions between smoke and meteorology during this event, and discuss the implications that increases in regional smoke may have on future meteorological conditions.
