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.

该项目的重点是研究大气中的黑碳（BC），这是主要的短期气候污染物之一。 将进行全面的多尺度模拟研究，以评估BC对城市和区域尺度的气候影响。 模型研究将应用于墨西哥城大都市区（MCMA），并使用NSF赞助的2006年MILAGRO期间获得的地面，飞机和卫星测量进行评估（巨型城市倡议：地方和全球研究观测）运动的MCMA。研究的目标是：（1）评估BC的辐射影响;（2）评估BC和共同排放物种的净辐射影响;（3）分摊BC主要排放源的区域辐射影响;以及（4）调查气候变化对空气质量和BC辐射影响的影响。 WRF-Chem模型将由国家环境预测中心（NCEP）再分析数据和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传输模型MOZART-4和GISS输出中插值。
