CEDAR: A Cedar Modeling Study of Global Change in the Mesosphere and Lower Thermosphere

该奖项支持开发三维模型，以进一步量化中层和低层热层对温室气体含量增加引起的高层大气全球变化的可能的热响应和动力响应。该奖项将建立在以前NSF奖项提供的模型开发支持的专业知识基础上。改进后的模型将包括适用于大范围CO2浓度的红外辐射传输的新参数化。改进工作还将包括修改由预测的全球变化扰动引起的辐射、动力和化学环境的反馈机制。

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.
