摘 要: 利用自行研制的光谱辐亮度响应度定标系统对CIMEL CE318的天空散射通道进行绝对定标,对于无偏675,870和1020 nm和三个偏振870 nm通道合成标准不确定度优于1%。对于同一台太阳辐射计,定标系数与NASA的相对偏差在±1.4%以内,说明了定标结果的可靠性。 A CIMEL CE318 is calibrated by using a new tunable laser-based facility for spectral radiance responsivity with combined standard uncertainties lower than 1%.The same CE318 is also calibrated by using a NASA lamp-illuminated integrating sphere source.Relative deviations between NASA and our calibration coefficients are within ±1.4%;which indicates that the proposed method is accurate.
