Accurate Shortwave Radiation Simulation with a Two-Layer Aerosol Model in Xinjiang Region     

Guan HUANG  Yonghang CHEN  Qiong LIU  Pengtao WANG  Qianshan HE  Qing HE  Shuai LI  Weiling SHAO  Ting FAN 《Journal of Meteorological Research》2024,(1):69-87

To harness the rich solar energy resources in Xinjiang Region of Northwest China, this study tries to address the issue of lack of downward surface shortwave radiation(DSSR) observations and the need to improve the accuracy of satellite retrieval and numerical simulation of DSSR under varied sky and meteorological conditions.(1) A two-layer aerosol model specific to Xinjiang was developed to capture the vertical distributions of aerosols based on multiple data sources including lidar, GPS soundi...  相似文献   

How to estimate isotope fractionations of a Rayleigh-like but diffusion-limited disequilibrium process?     

Zi Xuan Guan  Yun Liu 《Acta Geochimica》2023,(1):24-37

The Rayleigh distillation isotope fractionation(RDIF) model is one of the most popular methods used in isotope geochemistry. Numerous isotope signals observed in geologic processes have been interpreted with this model. The RDIF model provides a simple mathematic solution for the reservoir-limited equilibrium isotope fractionation effect. Due to the reservoir effect, tremendously large isotope fractionations will always be produced if the reservoir is close to being depleted. However, in real si...  相似文献   

大型射电望远镜的设计原则及一种新方案的建议     

王绶琯  郭成光 《天文学报》1964,(2)

本文从讨论现有各种大型射电望远镜系统出发,根据技术条件和研究工作的发展趋势,提出在设计中应当考虑的因素.按照这些考虑,提出了由一个中央大型抛物面天线和多个环状分布分立天线组合而成的系统,导出这种组合的设计公式,并以环的数目 N=6为例,计算了具体的天线方向图形空间谱,并算出为了调整方向图形所需的改正曲线,以及通过两种改正方法所得到的图形.这种系统有着多用途的特点.同时它可以适用于很宽的波长范围,而且通过增加环数可以得到不断的发展.文中讨论了这些特点,提出了一些问题,并且对实现这种方案的技术条件作了简要的叙述.  相似文献

英仙星群的研究,告诉我们以邻近的早型星群,它们的膨胀运动可以从观测中得出,这篇文章是沿着这路线的一个研究报导。蝎虎群处于l=45°-90°,b=0°-30°,包含有O至B5型的星,本文中所采的全部选自Henry Draper星表,所以限于m<8.3,因此,这一星群中,还可能有其他较暗的成员未被列入。谱型的类别,用了Yerkes系统。光度种类(luminosity class)亦然,全群的  相似文献
