对流层中的碳烟尘可以显著地改变晴空辐射强迫。使用扩展到一个简单的辐射计算和两个模型推导的硫酸盐气溶胶数据集，假设烟尘/硫酸盐质量比为0.05和0.1之间的影响进行了检查。化石。由燃料产生的煤烟引起的全球平均辐射强迫为正，对于一个数据集，其范围为+0.03到+0.24W m（-2），下估计值为煤烟/硫酸盐比为0.05的外部混合物，上估计值为煤烟/硫酸盐比为0.10的内部混合物。这些值与硫酸盐气溶胶造成的全球平均辐射强迫-0.34W m（-2）相比。煤烟还显着减少了半球间的差异，由于硫酸盐气溶胶的辐射强迫。如果要充分了解对流层气溶胶的气候作用，就必须很好地确定煤烟的性质和数量。
Carbonaceous soot within the troposphere can significantly modify the clear-sky radiative forcing. Using an extension to a simple radiation calculation and two model-derived sulfate aerosol data sets, the impact of an assumed soot/sulfate mass ratio of between 0.05 and 0.1 is examined. Fossil. fuel derived soot causes a positive global-mean radiative forcing which for one data set ranges from +0.03 to +0.24W m(-2) the lower estimate is for an external mixture with a soot/sulfate ratio of 0.05 and the upper estimate is for an internal mixture and a soot/sulfate ratio of 0.10. These values compare to a global-mean radiative forcing of -0.34W m(-2) due to sulfate aerosol. Soot also significantly reduces the interhemispherical difference in the radiative forcing due to sulfate aerosol. The nature and amount of soot must be well established if the climatic role of tropospheric aerosols is to be fully understood.
