摘要/Abstract

摘要：

许多光学工程都需要掌握实时大气参数廓线，用来预测大气透过率和大气背景辐射，而目前除了无线电探空外和大气遥感外，不易获得实时大气参数廓线。本文利用历年探空站点数据，并根据地面实时大气参数值，构建各高度层比例因子，得到实时大气参数廓线。以厦门地区为例，将模拟构建的实时温度、气压、水汽密度廓线及整层大气可降水量与实际探空廓线进行对比，表明：构造的对流层以下的温度廓线偏差小于2.5K，气压基本保持不变，水汽密度廓线在晴天条件下与真实廓线吻合较好，水汽总量偏差小于15%。此方法在某些光学工程中由一定的应用价值。

Abstract:

Some optical engineerings need real-time atmospheric parameter profiles to forecast atmosphere transmittance and atmospheric background radiation. It is not convenient and easy to obtain real-time atmospheric parameter profiles. A method was proposed to construct the atmospheric parameter profiles mode. The scale-coefficients at different heights were obtained based on the historical radiosonde-data and real-time ground-based data over years. Then the real-time atmospheric parameter profiles using the mode and the scale-coefficient were realized. Using Xiamen district as example, comparing the simulated profiles of temperature, pressure, water vapor density profiles and precipitable water vapor with the radiosonde profiles, the results show that the difference of temperature profile under troposphere is less than 2.5 K, the pressure doesn't change much, the water vapor density profiles are identical with rediosonde profiles in clear days and the difference of precipitable water is less than 15%. The proposed method can be used in some research programs to obtain real-time atmospheric parameters profiles.

Key words: real-time atmospheric parameter profiles, modelling, precipitable water
