This project focuses on the study of black carbon (BC) in the atmosphere, one of the major short-lived climate pollutants. Comprehensive multi-scale modeling studies will be conducted to assess the climate impacts of BC on urban and regional scales. Modeling studies will be applied to the Mexico City Metropolitan Area (MCMA) and evaluated using ground-, aircraft- and satellite-based measurements obtained during the NSF-sponsored 2006 MILAGRO (Megacity Initiative: Local and Global Research Observations) Campaign in the MCMA.The objectives of the research are to: (1) evaluate the radiative impacts of BC only; (2) assess the net radiative effects of BC and co-emitted species; (3) apportion the regional radiative impact of major BC emission sources; and (4) investigate the influences of climate change on air quality and on the radiative impact of BC. The WRF-Chem model will be driven by both the National Center for Environmental Prediction (NCEP) reanalysis data and the NASA GISS-E2-R model output, and chemical initial and boundary conditions will be interpolated from the global chemical transport model MOZART-4 and GISS outputs.

该项目的重点是大气中黑碳（BC）的研究，这是主要短暂的气候污染物之一。 将进行全面的多尺度建模研究，以评估卑诗省对城市和区域尺度的气候影响。 建模研究将应用于墨西哥城都会区（MCMA），并使用在NSF赞助的2006年Milagro（Megacity Initiative：Local and Global Research观察结果）中获得的基于地面，飞机和卫星的测量值进行评估。 （2）评估卑诗省和共同物种的净辐射作用； （3）比例分配BC排放源的区域辐射影响； （4）研究气候变化对空气质量和卑诗省辐射影响的影响。 WRF-CHEM模型将由国家环境预测中心（NCEP）重新分析数据和NASA GISS-E2-R模型输出驱动，化学初始和边界条件将从全球化学转运模型Mozart-4和GISS输出中插值。
