摘　　要：在全球变暖的背景下,全球的净全辐射监测越来越受到人们的重视,逐渐成为研究区域天气气候的重要手段。为了研究国产FS-J1型四分量净全辐射表在极地条件下的各项性能,于2017年4月10—23日在美国阿拉斯加巴罗地区(203.5°E,71.4°N)进行了为期2周的地面净全辐射量实时监测,并与极地地区应用较广的CNR4型四分量净全辐射表进行对比测试。结果表明:(1)在表面无结冰/霜条件下,国产仪器FS-J1型四分量净全辐射表在不同晴空和日夜条件下都表现出较好的精度和线性关系,各项参数与CNR4的相对误差和相关系数总体分别在5%以内和0.9以上。(2)受极地条件影响,FS-J1表面结冰/霜后,会对辐射变化的响应出现延迟,对总辐射表和地球辐射表分别能造成最大约25%和7%的相对误差。所以针对极地辐射站加设合适的通风加热装置、发展较为合理的误差订正方案仍是国产仪器以后需要改进的关键点。Under the background of global warming,the global net radiation monitoring is become more and more important.It has gradually become an important way to study regional synoptic conditions and climate.In order to evaluate the domestic FS-J1 four-component net radiometer,we tested it in Barrow,Alaska（203.5°E,71.4°N）from 10 to 23 April 2017,compared with the CNR4 four-component net radiometer,which is widely used in the polar regions.The results show that FS-J1 four-component net radiometer performs well in precision and linear correlation under different conditions of clearness and in both daytime and nighttime without icing/riming on surface.The relative error and correlation coefficient of parameters with CNR4 are within 5% and above 0.9,respectively.However,FS-J1 shows a delay in the response of the radiation change under the influence of polar condition when ice/rime forms on its surface.The relative errors of the pyranometer and pyrgeometer are up to 25% and 7%,respectively.Therefore,it is still a key point to improve the suitable ventilating and heating device for polar radiation stations,and the reasonable filtering method and parameterization scheme are also needed.
