摘要:

论文利用2017年东疆哈密地区红柳河黑戈壁地面高精度紫外辐射实测数据与美国NASA Langely研究中心大气科学数据中心提供的CERES_SYN1 deg_Ed4A产品数据,对卫星反演的紫外辐射A、B波段(UVA和UVB)数据在该地区的适用性进行了对比验证。结果表明:① 在日尺度上,该地区地面实测紫外辐射UVA和UVB与卫星反演数据之间的相关系数达0.9以上,其中在全天空情况下UVA平均偏差为1.15 W·m -2、UVB 平均偏差为0.03 W·m -2,晴天条件下UVA和UVB的平均偏差分别为0.93 W·m -2和0.03 W·m -2;② 在季节尺度上,实测和卫星反演UVA和UVB的偏差夏季最大,分别为2.04 W·m -2和0.05 W·m -2,春冬两季次之,秋季最小;③ 红柳河地区在春夏两季受到气溶胶光学厚度(AOD)影响较大,呈现显著负相关;④ 云量越大,紫外辐射削弱程度越大,在多云条件下地面实测与卫星反演UVA与UVB偏差最大,分别为1.73 W·m -2和0.05 W·m -2

Abstract:

:In this study, we compared the 2017 ground-based surface ultraviolet radiation in the UVA and the UVB bands of the Hongliuhe Black Gobi desert in Hami region of eastern Xinjiang Autonomous Region with the CERES_SYN1 deg_Ed4A product data provided by the NASA Langley Research Center Atmospheric Science Data Center. The results show that: 1) On a daily scale, the coefficient of correlation between the ground-based and the satellite-retrieved UVA and UVB fluxes is above 0.9. The daily mean bias of the ground-based observed data and the satellite-retrieved UVA and UVB fluxes are 1.15 W·m -2 and 0.03 W·m -2 under all-sky conditions, and 0.93 W·m -2and 0.03 W·m -2under clear sky. 2) Seasonally, the difference of UVA and UVB observed and retrieved by satellite is the largest in the summer, at 2.04 W·m -2 and 0.05 W·m -2 respectively, followed by the spring and the winter, and is the smallest in the autumn. 3) The Hongliuhe area was greatly affected by aerosol optical depth (AOD) in the spring and the summer, showing a significant negative correlation. 4) The degree of ultraviolet radiation attenuation increases with the cloud cover. Under cloudy conditions, the mean bias of ground measurements and satellite-retrieved data of UVA and UVB are the largest, at 1.73 W·m -2 and 0.05 W·m -2 respectively.
