Preliminary research on field measurement of spectral emissivity of rice in thermal infrared
水稻冠层热红外发射率的野外测量方法研究初报

The procedure and method of emissivity field measurement for rice were conducted using a portable Fourier transform infrared spectrometer.The results showed that rice emissivity value measured indoor was very close to 1.0,and no distinct emissivity characteristics were found in the spectral curves.Consequently,the field measurement should be carried out under generally clear sky conditions and low to moderate relative humidity,and the distance between the instrument and the objective should be shortened in ...
