    The variation of the optical depth of atmospheric aerosols has been analysed based on measurement data under different atmospheric conditions. The accuracy of Angstrom formula is estimated. The agreement of Angstrom formula with measurement data and the valid range of the Angstrom formula are discussed. The result shows that: 1) in the visible and near-infrared spectral regions only 20% of the measurement data are in close agreement with Angstrom formula; 2) when aerosol optical depth is smaller than 0.1, the Angstrom formula is essentially invalid; 3) using wavelengths 3800 A and 5000 A for the determination of Angstrom parameters, as suggested by WMO, may produce a larger relative error; 4) application of the Angstrom formula should be limited to the visible spectral region and turbid atmosphere; moreover, the Angstrom parameters should be determined by the use of multispeetral solar radiation data in the whole visible region instead of two wavelengths.

    本文根据在不同大气条件下获得的大量观测资料,分析了大气气溶胶光学厚度的变化;估计了Angstrom公式的精度,并在此基础上讨论了Angstrom公式和实测结果的符合程度以及Angstrom公式的适用范围。结果表明,在可见光和近红外范围内,Angstrom公式仅和20%左右的实测结果相符合。在气溶胶光学厚度小于0.1的洁净大气中,Angstrom公式基本上是不适用的。WMO建议使用3800埃和5000埃两个波长来确定Angstrom参数,一股会导致较大的误差。Angstrom公式的使用应限制在可见光区和比较浑浊的大气状况,并且在确定Angstrom参数时应当使用整个可见光波区范围内的多波段太阳辐射观测资料。
