Abstract Akmaev ATM-0003071This award supports the development of a three dimensional model to further quantify the possible thermal and dynamical response in the mesosphere and lower thermosphere predicted for the global change in the upper atmosphere caused by the increase in greenhouse gas content. The award will build upon the expertise provided by model development support by previous NSF awards. The improved model will included a new parameterization of infrared radiative transfer applicable to a wide range of CO2 concentrations. The improvement will also include feedback mechanisms that modify the radiative, dynamical and chemical environments resulting from the predicted global change perturbations.

摘要Akmaev ATM-0003071该奖项支持一个三维模式的发展，以进一步量化预测温室气体含量增加所引起的全球高层大气变化在中间层和低热层中可能的热和动力响应。该奖项将建立在由以前的NSF奖项提供的模型开发支持所提供的专业知识的基础上。改进后的模式将包括一个新的适用于大范围二氧化碳浓度范围的红外辐射传输的参数。改进还将包括反馈机制，这些反馈机制改变了预测的全球变化扰动造成的辐射、动力和化学环境。
