我们描述了根据 NASA 全球建模计划 (GMI) 开发的三维全球平流层化学模型，用于评估拟议的高速民用运输机队的排放可能对环境造成的影响。该模型是通过 GMI 团队成员的独特合作开发的。团队成员提供了代表各种物理和化学过程的计算模块，并通过与观察的广泛比较来分析模拟结果。团队成员的模块集成在一个计算框架内，允许在大规模并行计算机上进行可移植性和模拟。该模型框架的一个独特之处是能够互换和相互比较不同的子模块，以评估数值算法和模型假设对模拟结果的敏感性。在本文中，我们讨论了 GMI 工作的重要属性，并描述了 GMI 模型计算框架和代表物理和化学过程的数值模块。作为该概念的应用，我们分析了平流算法对平流层中类 NOy 源扩散的影响，该源模拟了在 17 至 20 公里之间飞行的商业超音速运输机队（高速民用运输机 (HSCT)）。
We describe the three-dimensional global stratospheric chemistry model developed under the NASA Global Modeling Initiative (GMI) to assess the possible environmental consequences from the emissions of a fleet of proposed high-speed civil transport aircraft. This model was developed through a unique collaboration of the members of the GMI team. Team members provided computational modules representing various physical and chemical processes, and analysis of simulation results through extensive comparison to observation. The team members' modules were integrated within a computational framework that allowed transportability and simulations on massively parallel computers. A unique aspect of this model framework is the ability to interchange and intercompare different submodules to assess the sensitivity of numerical algorithms and model assumptions to simulation results. In this paper, we discuss the important attributes of the GMI effort and describe the GMI model computational framework and the numerical modules representing physical and chemical processes. As an application of the concept, we illustrate an analysis of the impact of advection algorithms on the dispersion of a NOy-like source in the stratosphere which mimics that of a fleet of commercial supersonic transports (high-speed civil transport (HSCT)) flying between 17 and 20 km.
