Chemistry and Chemical Evolution of Atmospheres

小行星9216340 这是一个基础广泛的研究项目，重点是地球和其他行星大气层的化学和化学演变。 这项工作涉及发展化学动力学大气模型，测量大气成分，重点是碳氢化合物（气相色谱法）和羟基自由基（活性滴定法），以及发展大气起源的统一理论。 研究方案的主要领域是：（a）实地测量非甲烷碳氢化合物（气相色谱法）和羟基自由基（活性滴定法），作为对国际全球大气化学项目的贡献。 (b)开发化学动力大气模型和地球化学循环模型，以帮助解释（a）中获得的数据。 (c)研究行星大气层的现状、起源和演变，包括大型碰撞和表面-大气层反应的影响，并考虑到确定初始行星挥发物含量的早期太阳系过程。

9216340 Prinn This is a broad-based research project focused on the chemistry and chemical evolution of the atmospheres Earth and other planets. The work involves development of chemical-dynamical atmospheric models, measurements of atmospheric constituents focussing on hydrocarbons (gas chromatography) and hydroxyl radicals (active titration), and development of a unified theory for the origin of atmospheres. The principal areas in the research program are: (a) Field measurements of nonmethane hydrocarbons (gas chromatography) and hydroxyl radical (active titration) as contributions to the International Global Atmospheric Chemistry (IGAC) Project. (b) Development of chemical-dynamical atmospheric models and biogeochemical cycling models to aid interpretation of data obtained in (a). (c) Studies of the current state and origin and evolution of planetary atmospheres including effects of large collisions and surface-atmosphere reactions, and taking into account early solar system processes determining initial planetary volatile contents.
