In the paper, we propose a new method of identifying the clear sky based on the Atmospheric Emitted Radiance Interferometer (AERI). Using the Atmospheric Radiation Measurement (ARM) Mobile Facility (AFM) dataset in Shouxian in 2008, we simulate the downwelling radiances on the surface in the 8-12m window region using Line-By-Line Radiative Transfer Model (LBLRTM), and compare the results with the AERI radiances. The differences larger (smaller) than 3mW (cm2 sr cm1 ) 1 suggest a cloudy (clear) sky. Meanwhile, we develop the new algorithms for retrieving the zenith equivalent cloud base height (CBH e ) and the equivalent emissivity (e), respectively. The retrieval methods are described as follows. (1) An infinitely thin and isothermal blackbody cloud is simulated by the LBLRTM. The cloud base height (H) is adjusted iteratively to satisfy the situation that the contribution of the blackbody to the downwelling radiance is equal to that of realistic cloud. The final H is considered as CBH e . The retrieval results indicate that the differences between the CBH e and observational cloud base height (CBH) are much smaller for thick low cloud, and increase with the increasing CBH. (2) An infinitely thin and isothermal gray body cloud is simulated by the LBLRTM, with the CBH specified as the observed value. The cloud base emissivity (c) is adjusted iteratively until the contribution of the gray body to the downwelling radiance is the same as that of realistic cloud. The corresponding gc is ge . The average ge for the low, middle, and high cloud is 0.967, 0.781, and 0.616 for the 50 cases, respectively. It decreases with the increasing CBH. The retrieval results will be useful for studying the role of cloud in the radiation budget in the window region and cloud parameterizations in the climate model.

目的研究周边建筑物对大跨度穹顶结构屋面风压的干扰效应,揭示周边干扰建筑的距离对干扰效应的影响规律。方法选取一栋单体大跨度穹顶结构及2种间距比下的风压分布特性进行数值模拟研究,并通过风洞试验验证了数值模拟的可靠性,再基于Fluent数值模拟平台,考虑4种风向角和7种间距比,分析了不同间距比下单体干扰建筑对大跨度穹顶结构屋面风压分布的影响。结果研究表明:干扰建筑对屋面产生最不利影响的风压区域发生在穹顶中心周围;不同间距比下,干扰建筑对屋面的最不利风压的影响也不一样;间距比小于1.2时,60°风向角为最不利风向角;间距比为1.2~1.4时,90°风向角为最不利风向角;当间距比大于1.4时,30°风向角为最不利风向角。结论与规范对比,受周边建筑干扰后,最不利风向角下穹顶表面最不利风荷载影响区域的风压会增大1.5倍;笔者的研究结果可为大跨度穹顶结构的抗风设计提供参考。
