Field measurements of meadow surface emissivity spectra at the Xilinhaote grassland of China.

The meadow surface emissivita spectra of the Xilinhaote grassland of China is one of the key factors for calibration of thermal infrared remote sensors using land surface.Based on the iterative spectrally smooth temperature/emissivity separation(ISSTES) algorithm,Xilinhaote meadow surface emissivity spectra were measured using a BOMEM MR154 Fourier transform spectroradiometer and infrared golden board.Emissivity spectra data were obtained at different times and land surface conditions.With these measured emissivity spectra,all of the mainstream thermal infrared remote sensors can be calibrated and validated using Xilinhaote meadow surface.
