基于统一模型的典型地表红外辐射特性对比研究
COMPARATIVE STUDIES OF IR RADIATION CHARACTERISTICS OF TYPICAL GROUND BASED ON A UNIFORM MODEL
摘要
根据自然地表的稳态平衡方程,将干燥裸地、潮湿裸地、低植被覆盖地表统一为一种模型.综合考虑了各种自然因素,采用了蒙特卡罗方法,模拟了自然地表辐射温度的周期性变化以及各自然因素对红外辐射温度均值及其方差(起伏)的影响.实验结果表明此模型能较好地模拟这几种典型地表的红外热辐射特性.
Abstract
The uniform model of three kinds of typical grounds, i.e. dry bare ground, wet bare ground and ground covered by low vegetation, was constructed based on the heat balance equation of ground surfave. All kinds of factors were under consideration. In calculation, the Monte Carlo simulation was used to analyze the above natural ground's periodical infrared radiance statistics and the influence on the average value and variance (fluctuation) of the infrared radiation temperature caused by the above circumstance factors. The experimental results show that the model can simulate the infrared radiance statistics of the above typical ground fairly well.
