| 中文摘要 |
| 大规模的太阳分光地基联网观测不但能够直接为该项研究提供基础数据,同时也可为卫星遥感提供地表订正.利用性能优越的LED型太阳光度计,依托中国生态研究网络(CERN)分布在中国各地的观测站,建立了标准的太阳分光辐射观测网.利用Langley定标法结合量值传递定标法对观测网所有光度计的标定方法及误差分析表明,不同光度计间的同步观测结果(相对标准偏差小于3%)以及与CIMEL光度计的观测结果间(相对偏差小于5%)有很好的一致性,证实了观测结果的准确性以及该类型光度计及其观测网的稳定性和可靠性. |
| 英文摘要 |
| Much of the current uncertainty in the quantitative assessment of the climate and environment change is due to our lack of knowledge of the aerosol,for which the large-scale sun hazemeter ground-based network directly provides basic data.The data also can revise the results of the satellite remote sensing.Depending on the stations of CERN,the standard network was first built in China.The accurate and reliable hazemeter(LEDs) was uniformly used in the network.The hazemeters were calibrated by Langley plot method and transfer calibration and were uniformly checked.The AODs,which were synchronously retrieved from hazemeters(RSD<3%) and CEMIL(RSD<5%),were coherent and comparable.The stability and reliability of the hazemeters and the network was approved. |
