The relevance of polarization measurements in the near uv and visible regions of the electromagnetic spectrum in investigations of the effects of the atmospheric aerosol and the reflective properties of the ground, intermediate layers of the atmosphere, and the atmosphere as a whole on the ambient radiation field is discussed. The salient features of a photoelectric skylight polarimeter characterized by its adaptability to balloon-borne measurements of the degree of linear polarization and relative intensity variations in four narrow spectral intervals (bandwidth approximately 150 A) centered on lambdalambda 3270 A, 3975 A, 500 A, and 6120 A are described. Preliminary results of measurements obtained in a balloon experiment staged at Page, Arizona (36 degrees 57'N, 111 degrees 27'W, 1300 m above msl) on 30 March 1965 are presented.
讨论了在电磁光谱的近紫外和可见光区域进行偏振测量，对于研究大气气溶胶以及地面、大气中间层和整个大气的反射特性对周围辐射场的影响的相关性。描述了一种光电天光偏振计的显著特点，该偏振计适用于气球携带测量四个以λ3270Å、3975Å、5000Å和6120Å为中心的窄光谱区间（带宽约150Å）内的线性偏振度和相对强度变化。给出了1965年3月30日在亚利桑那州佩奇（北纬36度57分，西经111度27分，平均海平面以上1300米）进行的气球实验中获得的测量初步结果。
