摘要 差分法(extinction minus scattering)是气溶胶吸收系数的常用测量方法之一。针对气候变化对气溶胶吸收系数的敏感性要求,理论分析了基于光腔衰荡光谱测量消光系数、散射系数的不确定度,推导了气溶胶吸收系数的不确定公式,并讨论了不同气溶胶单次散射联合反照率下气溶胶吸收系数的不确定度值,为研究大气气溶胶吸收对气溶胶辐射强迫以及气候强迫的影响提供参考。 Extinction minus scattering is an important method for aerosols absorption measurement. Due to sensitivity of climate change depending on aerosols absorption, uncertainty of extinction and scattering coefficient is analyzed, and uncertainty equation of aerosols absorption with extinction minus scattering is established. Under different coalbedo, uncertainty value of aerosols absorption is discussed. The result would play an important role in evaluating aerosols radiation forcing and giving useful reference for climate forcing effect.
