The Tenth (10th) International GEOS-Chem Meeting (IGC10); Saint Louis, Missouri; June 7-10, 2022

该项目将为参加2022年6月7日至10日在密苏里州圣路易斯举行的第十届国际GEOS-Chem会议（IGC10）的学生、早期职业科学家和实验科学家提供旅行支持。这次会议汇集了GEOS-Chem建模社区的科学家、学生和其他人员，交换信息，为与气候动力学、生物地球化学和空气质量有关的大气成分建模的基础研究提供信息和刺激。GEOS-Chem是一个开源的全球大气成分三维模型，被全球160多个研究小组积极使用，其中包括美国大学的50多个研究小组。由15位美国大学教授组成的GEOS-Chem指导委员会提供模型管理指导。国际GEOS-Chem会议每两年举行一次，是全球大气化学建模界的重大活动，约有250名与会者，主题范围非常广泛。GEOS-Chem的应用涵盖了非常广泛的大气成分问题，包括氧化剂、气溶胶、碳气体、平流层化学、汞、持久性有机污染物等。GEOS-Chem与气候和天气模式相联系，用于研究化学-气候-生态系统相互作用、化学数据同化和空气质量预报。在GEOS-Chem会议上，早期职业科学家和研究生的口头报告是优先考虑的，这为许多人提供了第一次在大量国际观众面前展示他们工作的机会。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This project will provide travel support to students, early career scientists and experimental scientists to attend the 10th International GEOS-Chem Meeting (IGC10) in St. Louis MO on June 7-10, 2022. This meeting brings together scientists, students, and others in the GEOS-Chem modeling community to exchange information that will inform and stimulate fundamental research in the modeling of atmospheric composition with links to climate dynamics, biogeochemistry, and air quality.GEOS-Chem is an open-source global 3-D model of atmospheric composition used actively by over 160 research groups around the world, including over 50 research groups in US universities. Guidance for model management is provided by a GEOS-Chem Steering Committee including 15 US university professors. International GEOS-Chem meetings have been held every two years and are major events for the global atmospheric chemistry modeling community, with about 250 attendees and a very broad range of topics. Applications of GEOS-Chem span a very wide range of atmospheric composition problems including oxidants, aerosols, carbon gases, stratospheric chemistry, mercury, persistent organic pollutants, and others. GEOS-Chem links with climate and weather models for studies of chemistry-climate-ecosystem interactions, chemical data assimilation, and air quality forecasting. Oral presentations by early-career scientists and graduate students are prioritized at GEOS-Chem meetings, providing for many a first opportunity to present their work in front of a large international audience.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
