solar zenith angle

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的变化主要是由近红外波段反射率随太阳天顶角的变化引起的；

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的增加接近线性增加；

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、卫星天顶角等因素呈反相关，与相对方位角无必然联系。

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和主要的大气气体吸收是不敏感的。

The results are as follows: ( 1) Solar incident angle, especially zenith angle can change the shape of BRDF.

具体研究结果如下：（1）太阳入射角度，特别是太阳天顶角能改变水体二向反射分布函数的形状。

The required input to the parameterization includes precipitable water, concentration of carbon dioxide amount, ozone amount, cloud amount, cloud visible optical depth, solar zenith angle and surface albedo.

计算所需要的输入变量有：大气可降水量，二氧化碳含量，臭氧总量，云量，云的光学厚度，太阳天顶角，地表反射率。

Daily variations of UV B radiation are greatly controlled by the solar zenith angle ( SZA), ozone and the sky conditions.

云和太阳高度角控制着UV－B辐射通量日变化过程。
