摘　　要：为揭示高光谱辐射反演气溶胶光学厚度并研究其质量控制技术,文章基于安徽合肥2021-06-05 T 08:00/2021-06-05 T 16:00晴天数据,采用实际缺测检查、理论范围检查、统计控制等质量控制方法开展了研究。结果表明:研究期间数据无缺测;在理论范围检查剔除的数量极少,并且剔除数据具有时间一致性;统计控制可以有效地将直接辐照度波动值剔除,使反演产品更为准确合理;质量控制后6个波段气溶胶光学厚度均呈现先上升到正午时刻达到最大值后再下降的相同趋势,并且气溶胶光学厚度随波长增大而减小。In order to reveal the aerosol optical thickness of hyperspectral radiation inversion and study its quality control technology,the author anducted research based on the fine day data from 8:00 to 16:00 on June 5,2021 in Hefei,Anhui Province,by quality control methods such as actual missing test inspection,theoretical range inspection and statistical control.The results indicated that there were no missing data during the study period.In the theoretical range,the number of removals was very small,and the removal data had temporal consistency.Statistical control could effectively eliminate the direct irradiance fluctuation value,enabling the inversion products were more accurate and reasonable.After quality control,the aerosol optical thickness of all six bands had the same trend of first increasing to the maximum value at noon and then decreasings,and the aerosol optical thickness decreased with the increase of wavelength.
