例句与用法
- Based on the spectral irradiance measured with the sun - atmosphere ultraviolet spectrum radiometer ( sauvs ) developed by the institute of atmosphere physics and the changchun institute of optics and fine mechanics , chinese academy of sciences , measuring the direct and scatter irradiance spectrum of ultraviolet waveband which arrives in beijing global surface , giving a method of retrieving the aerosol optical depth ( aod ) and put up with primary results that exponential function can fit the retrieval results according to its visibility , putting forth different coefficients and functions on variable visibility , also giving a primary analysis on the aod in dust - storm day and some contrast between sun - day and dust - storm day , analyzing the ratio between scatter and total irradiance , and its relationship with atmosphere mass and total atmosphere optical depth , lastly contrasting with the survey results by aeronet beijing station , the results of retrieval is in reason , this work gives some help in researching the co - effect of aerosol - radiance - climate and makes preparation for further survey on the radiance characteristics of dust
利用中国科学院大气物理研究所与长春光学精密机械研究所合作研制的太阳?大气紫外光谱辐射计( sauvs ) ，测量到达北京地表的太阳直接和散射紫外光谱辐射，导出了大气气溶胶的光学厚度。初步结果表明：北京紫外波段大气气溶胶的光学厚度在绝大部分情况下随波长的增加而单调减小，用指数函数可以较好地拟合反演结果，统计得到了三个水平能见度状况下拟合函数的系数值和公式表达式；初步分析了扬沙、浮尘、沙尘暴天气条件下气溶胶光学厚度的特点，并与一般晴朗天气条件下的气溶胶光学厚度特点做了比较分析；分析了太阳紫外谱辐射中散射辐射与大气质量、大气总光学厚度的定性关系和定量表达式；最后与全球气溶胶监测网络( aeronet )北京站的资料做比对，表明反演结果基本合理。
