A joint project (Parameterization of the Aerosol Climatic Effect, PACE) between experimentalists and modelers who have expertise in aerosol chemistry, cloud microphysics, radiative transfer and climate modeling has recently been initiated to address the issue of aerosol interaction with clouds, referred to the aerosol indirect effect. The PI proposes to compare ACE-2 field campaign data with cloud properties and radiative fluxes simulated by the NASA GISS SCM along with that simulated by other models. The objectives are to rigorously assess the models and develop and test more realistic schemes for representing aerosol-cloud-radiation interactions in climate models. The work is important because it will contribute to narrowing the large range of uncertainty in model simulations of the indirect effects of anthropogenic aerosols, thereby facilitating more reliable predictions of global and regional climatic change.

最近，在气溶胶化学、云微物理学、辐射传输和气候模拟方面具有专门知识的实验人员和模拟人员之间发起了一个联合项目（气溶胶气候效应参数化），以解决气溶胶与云的相互作用问题，即气溶胶间接效应。PI建议将ACE-2实地活动数据与NASA GISS SCM沿着的云特性和辐射通量模拟数据与其他模式模拟数据进行比较。其目标是严格评估模型，并制定和测试在气候模型中代表气溶胶-云-辐射相互作用的更现实的方案。这项工作很重要，因为它将有助于缩小人为气溶胶间接影响的模型模拟中的大范围不确定性，从而促进对全球和区域气候变化进行更可靠的预测。
