SGER: Black Carbon Aerosol Measurements in the Coastal STRatocumulus Imposed Perturbation Experiment (CSTRIPE) Program

这个探索性研究（SGER）项目的小赠款涉及到在海岸线积云扰动实验（CSTRIPE）期间使用单粒子烟尘光度计（SP2）逐粒子测量气溶胶黑碳。CSTRIPE的空中测量将于2003年7月在加州蒙特雷海岸外的海军跨学科遥控飞机研究中心（ONR/CIRPAS）双水獭研究飞机上进行，为期三周。飞行还将在污染严重的圣华金河谷，加州大陆地区进行，以检查烟雾和城市/工业羽流产生的黑碳。黑碳颗粒具有很强的吸收性，被怀疑是烟霾和云层辐射强迫的主要决定因素。结果将提高我们的微物理和光学特性的传输气溶胶层及其对气候的影响的理解。该项目的更广泛影响包括一个独特而有趣的数据集，可供广泛的研究人员使用，这些研究人员对高吸收性黑碳对气溶胶和云的辐射特性的影响感兴趣，对气候可能产生深远的影响。该项目还涉及与美国和墨西哥私立和公立学术机构的研究人员合作，包括研究生的亲身参与。

This Small Grants for Exploratory Research (SGER) project involves measurements of aerosol black carbon on a particle-by-particle basis using the Single Particle Soot Photometer (SP2) during the Coastal STratocumulus Imposed Perturbation Experiment (CSTRIPE). Airborne measurements for CSTRIPE will be made from the Office of Naval Research Center for Interdisciplinary Remotely-Piloted Aircraft Studies (ONR/CIRPAS) Twin Otter research aircraft over three weeks in July 2003 off the coast of Monterey, California. Flights will also be performed over the heavily polluted San Joaquin Valley, California continental area to examine black carbon emanating from smoke and urban/industrial plumes. Particulate black carbon is highly absorptive, and suspected to be a major determinant of the radiative forcing due to haze and cloud layers. Results will improve our understanding of the microphysical and optical properties of transported aerosol layers and their influence on climate. Broader impacts of this project include a unique and interesting data set available to a wide range of researchers interested in the impact of highly absorbing black carbon on the radiative properties of aerosols and clouds, with potentially far-reaching implications for climate. The project also involves collaborations with researchers at private and public academic institutions in the U.S and Mexico, including hands-on graduate student participation.
