| 摘 要： | 本文对野外现场测定自然表面比辐射率的方法进行了理论分析和观测实验.结果表明文献1]的测量方法在估计比辐射率时偏高而使表面温度估计偏低,对原方法改进后可得到很好的改善;实验结果与理论计算值有很好的一致性,以部分计算值代替实测值,可减少实测项目,使观测方案进一步简化且仍保持良好的精度.应用改进后的方法,我们在“黑河试验”现场测定了几种不同下垫面的比辐射率.

| Abstract: | In this paper, the method of measuring the natural surface emissivity is analysed and the ex-periment result reported. Theoretical analysis shows that the Jing's method will ovrestimate the emissivity and underestimate the surface temperature. Some improvements have been made to obtain the more realistic surface emissivity. Using the improved method, the surface emissivities for several underlying surfaces were measured over the HEIFE (Heihe Field Experiment) area. |
