Travel Grant: Enabling Students and Early-Career Scientists to Attend the Eleventh (11th) International GEOS-Chem Meeting (IGC11); Saint Louis, Missouri; June 11-14, 2024

该项目将支持学生和早期职业科学家参加第11届国际GEOS-Chem会议（IGC 11）。GEOS-Chem是一个开源的全球大气成分3D模型，被全球数百个研究小组使用，其中包括美国大学的50多个研究小组。国际GEOS-Chem会议通常每两年举行一次，是全球大气化学模拟界的重大活动，约有250人参加，主题广泛。大气化学建模是一项重大的科学和计算挑战，因为需要模拟数百种气体和气溶胶化学物质，这些化学物质彼此严格耦合，并在所有尺度上与运输相互作用。GEOS-Chem最近（在美国国家科学基金会的支持下）被纳入社区地球系统模型（CESM），这是一个完全耦合的全球气候模型，提供了地球过去，现在和未来气候状态的最先进的计算机模拟。第11届国际GEOS-Chem会议（IGC 11）将于2024年6月11日至14日在圣路易斯的华盛顿大学举行。该提案要求的资金将专门用于为博士生，博士后和其他早期职业科学家提供部分旅行支持。差旅费将根据需求、成绩、差旅性质和促进多样性的情况作为单独拨款支付。由于美国大学团体的大量参与和GEOS-Chem社区的合作，该会议对考虑学术生涯的研究生和博士后特别有价值。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估来支持。

This project will support the attendance of students and early-career scientists at the 11th International GEOS-Chem Meeting (IGC11). GEOS-Chem is an open-source global 3-D model of atmospheric composition used by hundreds of research groups around the world, including over 50 research groups in US universities. The meeting will inform and stimulate fundamental research in modeling of atmospheric composition with links to climate dynamics, biogeochemistry, and air quality.International GEOS-Chem meetings typically have been held every two years and are major events for the global atmospheric chemistry modeling community, with about 250 participants and a broad range of topics. Modeling of atmospheric chemistry is a grand scientific and computational challenge because of the need to simulate hundreds of gaseous and aerosol chemical species stiffly coupled to each other and interacting with transport on all scales. GEOS-Chem was incorporated recently (with support from NSF) as a chemical module in the Community Earth System Model (CESM), a fully coupled, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and future climate states. The 11th International GEOS-Chem Meeting (IGC11) will be held on June 11-14, 2024, at Washington University in St. Louis. The funds requested by this proposal will be specifically used to provide partial travel support for PhD students, postdocs, and other early-career scientists. Travel funds will be disbursed as individual allocations on the basis of demand, merit, the nature of travel, and the promotion of diversity. The meeting is especially valuable for graduate students and postdocs contemplating academic careers because of the large participation from US university groups and the collegiality of the GEOS-Chem community.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.
