Development of a global-scale aerosol model coupled with atmospheric general circulation model and evaluation of climate effects of black carbon

我们开发了一种新的炭黑老化参数。利用我们的参数化方法，我们发展了一个全球尺度的气溶胶模式，它与大气环流模式相耦合，可以描述黑碳混合态的时间演化。我们还利用在东亚地区进行的飞机测量和模型模拟，研究了黑碳的运输和清除过程。通过观测对模型计算进行了验证，并对黑碳的空间分布及其气候效应进行了评价。

We have developed a new parameterization of black carbon aging. Using our parameterization, we have developed a global-scale aerosol model coupled with atmospheric general circulation model, which can represent a time evolution of the mixing state of black carbon. We have also examined transport and removal processes of black carbon using aircraft measurements conducted over East Asia and model simulations. We have validated the model calculations by the observations and evaluated the spatial distribution of black carbon and its climate effects.
