摘　　要：分析了太阳光度计测量大气气溶胶光学厚度时,由于校正系数的不确定性而产生的误差。利用推导的误差分析公式,模拟了校正系数在不同相对误差的情况下导致的气溶胶光学厚度的绝对误差;模拟结果显示,校正系数的相对误差小于+2%时可以满足气溶胶光学厚度的测量精度。The errors of atmospheric aerosol optical thickness obtained from Sun-photometer measurements, due to uncertainties of calibration coefficients, are analyzed. The precise formulae of errors analysis are deduced. The numerical experiments are carried out to investigate the absolute errors of aerosol optical thickness, caused by uncertainty of calibration coefficients. The simulative results indicate that calibration errors of less than ＋2% are suitable for aerosol optical thickness measurements.
