红外波段大气水汽对辐射能量影响的定量分析

水汽分子对地面发射辐射能量具有强力的吸收作用,吸收使辐射能量衰减,造成传感器接收到的地面辐射亮度值下降,但水汽分子时刻运动并引起浓度发生变化,浓度的改变使地面发射辐射能穿过大气层时随之发生变化。因此该文利用物理原理,探讨了大气中水分子的运动与其浓度的关系,以及大气中水分子浓度变化引起水汽分子吸收能量和传感器获取亮度值的变化规律。

Quantitative Analysis of Radiation Energy of Atmospheric Vapor in Infrared Band

Water vapor molecules can strongly absorb radiation energy emitted from the surface of the earth,this absorption will cause the sensor's decrease of the energy but the constant changes of water vapor molecules always cause its thickness,and this change will also alter radiant energy from the earth through atmosphere.This paper is to,by applying physical principle,to discuss the relationship between the movement of water vapor molecules in the atmosphere and their thickness,and the regular patterns of the ch...
