Transfer of Greenhouse and Other Trace Gases to the Oceans, Marine Stratus, and Sea Spray Aerosols

ATM-9504481雅各布森这个项目是由教师早期职业发展(CALEAR)计划资助的。它由研究和教育部分组成。在研究部分，将研究二氧化碳、硫酸、硝酸等痕量物种从大气到海水、海雾气溶胶和海洋层状物的转移。然后，所得到的信息将用于区域和全球计算机模拟。这将导致在气候模型中更好地处理大气-海洋二氧化碳交换，并更好地理解海洋喷雾颗粒与大气之间的微量气体交换。通过气体吸收生长的颗粒物通过减弱短波辐射直接影响气候。这种颗粒还可以从气相中去除一些酸，并向气相释放其他酸。为了进行这些研究，现有的化学、微物理和动力学计算机程序将被使用、改进并重新插入到更大的模拟系统中。将进行中尺度和全球计算机模拟以及敏感性研究，并对结果进行分析。在教育部分，将开发五门课程，涵盖(1)城市、区域和全球空气污染科学，(2)大气污染计算机模拟，(3)气象学和大气环境，(4)云微物理和化学，以及(5)大气辐射传输。此外，PI将致力于改善课堂交流，为课程项目编写程序并建立计算机实验室，评估课程和实验室对学生学习的影响，鼓励来自不同学科和代表性不足群体的学生参加课程，努力促进本科教育，为本科生和研究生提供建议，并鼓励学生参与研究项目。最后，他将开发一本课程教科书，并要求学生在一些课程中参与一个小型研究项目。

ATM-9504481 Jacobson This project is funded through the Faculty Early Career Development (CAREER) program. It consists of a research and an educational component. In the research part, the transfer of carbon dioxide, sulfuric acid, nitric acid, and other trace species from the atmosphere to ocean water, sea spray aerosols, and marine stratus will be studied. The resulting information will then be used in regional and global computer simulations. This will lead to a better treatment of atmosphere-ocean carbon dioxide exchange in climate models and to a better understanding of trace gas exchange between sea spray particles and the atmosphere. Particles that grow by gas absorption affect climate directly by attenuating short-wave radiation. Such particles also remove some acids from and release other acids to the gas phase. To carry out these studies, existing chemical, microphysical, and dynamical computer programs will be used, improved, and re-inserted into a larger modeling system. Mesoscale and global computer simulations as well as sensitivity studies will be carried out, and the results analyzed. For the educational component, five courses will be developed covering (1) the science of urban, regional, and global air pollution, (2) computer modeling of atmospheric pollution, (3) meteorology and the atmospheric environment, (4) cloud microphysics and chemistry, and (5) atmospheric radiative transfer. Furthermore, the PI will work to improve classroom communication, write programs for and set up computer laboratories for course projects, evaluate the effects of courses and laboratories on student learning, encourage students from diverse disciplines and underrepresented groups to participate in courses, work to foster undergraduate education, advise undergraduate and graduate students, and encourage students to participate in research projects. Finally he will develop a course textbook and require students to take part in a small research project in some courses.
