Land surface emissivity and atmospheric transmittance are the two key parameters which are used to retrieve LST. 大气透过率和地表比辐射率是求解地表温度的两个关键参数。
An instrument system for atmospheric transmittance by measuring solar irradiance in the visible and near-infrared spectral range was developed. 通过测量太阳辐射值计算整层大气透过率的方法简单易行且精度高。
