0004471Pinker Description: This award supports a US-India cooperative research project on Aerosol Optical Characterization and Investigation of Aerosol Radiative Forcing at the Surface and Top of the Atmosphere. The collaborators are Professor Rachel Pinker, University of Maryland and Professors G. Pandithurai and P.C.S. Devara, Indian Institute of Tropical Meteorology (IITM), Pune. The effect of radiative forcing by anthropogenic aerosols is one of the largest sources of uncertainty in climate prediction, particularly for poorly understood tropical aerosols. The PIs propose to add to the knowledge of aerosol optical characteristics through direct observation of the forcing at a tropical site. A radiometer from the US PI's home institution for characterizing aerosol optical properties will be deployed in India to augment existing IITM instrumentation for both active and passive remote sensing of aerosols. Scope: This research further enhances current collaborative efforts between the University of Maryland and the IITM on radiative effects of aerosols. Dr. Pandithurai spent two years as a postdoctoral fellow at the University of Maryland and worked in the areas pertinent to this research. The proposed activity will provide a coherent set of observations on aerosol optical properties, their vertical distribution, and their radiative effects. It will also help extend the results obtained from the Indian Ocean Experiment (INDOEX) to other continental regions. This award is jointly supported by the Division of International Programs and the Division of Atmospheric Sciences.

0004471 Pinker描述：该奖项支持美国-印度合作研究项目气溶胶光学特性和大气层表面和顶部气溶胶辐射强迫的调查。 合作者是马里兰州大学的雷切尔·平克教授和G. Pandithurai和P.C.S. Devara，印度热带气象研究所（IITM），浦那。 人为气溶胶的辐射强迫效应是气候预测中最大的不确定性来源之一，特别是对热带气溶胶知之甚少。 PI建议通过直接观测热带站点的强迫来增加气溶胶光学特性的知识。 将在印度部署一台来自美国PI所在机构的用于表征气溶胶光学特性的辐射计，以增强现有的IITM仪器，用于气溶胶的主动和被动遥感。 范围：这项研究进一步加强了马里兰州大学和IITM在气溶胶辐射效应方面的合作。 Pandithurai博士在马里兰州大学做了两年博士后研究员，并在与这项研究有关的领域工作。 拟议的活动将提供一套关于气溶胶光学特性、其垂直分布及其辐射效应的连贯观测。 它将 这也有助于将印度洋实验（INDOEX）的结果推广到其他大陆区域。 该奖项由国际计划司和大气科学司共同支持。
