The results show that the detectable stellar magnitude limits linearly increase with observing height and solar zenith angle. 结果表明:可探测星等极限值随观测高度和太阳天顶角(SZA)的增加接近线性增加;
As illustrated in our sensitivity study and demonstrated in real measurements, the transmittance ratio at selected wavelengths is insensitive to solar zenith angle and major atmospheric gaseous absorption. 敏感性试验和实际观测表明,所选择波段的透射比对太阳天顶角(SZA)和主要的大气气体吸收是不敏感的。
There exist negative correlation between the optical thickness of effective radiation layer and the droplet effective radius near cloud top, solar zenith angle and satellite zenith angle, not obvious for the relative azimuth angle. 有效辐射层的光学厚度与云上层有效粒子半径、太阳天顶角(SZA)、卫星天顶角等因素呈反相关,与相对方位角无必然联系。
In this paper, experimental formulae of the critical frequencies of the E-layer in mid-latitudes and of the distribution of electron density in the lower ionosphere are found. These formulae are expressed in terms of the sunspots number, the solar zenith angle and the local time. 本文给出了计算中纬E层临界频率(f(0E))和低电离层的电子密度分布与太阳天顶角(SZA)、太阳黑子数、地方时之间关系的经验公式。
Albedo is bigger over Gobi site than that over Oasis site. Variation of albedo with solar zenith angle is mainly caused by near-infrared albedo. 绿洲上的反射率小于戈壁上的,戈壁上反射率随太阳天顶角(SZA)的变化主要是由近红外波段反射率随太阳天顶角(SZA)的变化引起的;
