太阳天顶角 meaning in English
solar zenith angle
sun zenith angle
Examples
- The results show good performance between vis , irl , sun zenith and net surface radiation . the correlation coefficient is up to 0 . 8259
通过理论部分推导出的关系可以看出：地面净辐射与太阳天顶角、地面及云面反照率等因子有关。 - In this paper , the solar and land - atmosphere radiation rates are calculated by modtran3 model and satellite observation as well as surface data , solar direct irradiance infrared irradiance solar heating rate and infrared cooling rate were calculated from 43 samples of sunshine day and 5 samples of cloudy day 3 samples of rainy day of different latitudes in 12 stations . the paper analyzed solar heating rate and infrared cooling rate in sunshine day , the factors such as zenith angle , water vapor and latitude were found out correlating with solar heating rate and infrared cooling rate . solar heating rate and infrared cooling rate change on the same day and at the same station
在对晴空大气的计算中，本文对太阳的直接辐射与地气系统的红外辐射状况进行了分析，并讨论在不同的大气状况下太阳加热率和红外冷却率的情况，找出与太阳加热率和红外冷却率变化相关较大的因子?太阳天顶角和水汽条件、纬度；本文还进一步分析了不同纬度样本的太阳加热率与红外冷却率日变化及有云、有雨情况下太阳加热率和红外冷却率的变化情况：另外，文中通过改变二氧化碳在大气中含量的方法，讨论了它对太阳加热率与红外冷却率的影响。 - A two stream model has been used to calculate the variation of optical depth and their effects to ultraviolet radiation of each extinction material . with the model , the relation among season , solar zenith angle and ultraviolet radiation has been discussed , and the variation of ultraviolet radiation under different clouds has also been studied . the comparative research of ultraviolet radiation among kunming , beijing and other abroad area at the same latitude has also been done
