We have analyzed the relationship between the snow spectrum and snow contaminants. It is found that from 350nm to 850nm snow reflectance dramatically decreases with increase in concentrations of contaminants in snow. The results show that snow reflectance at 384nm logarithmically decreases with increase in the snow contaminants while the reflectance at 1495nm exponentially increases with the snow contaminants. Besides, we have selected six bands according to the center wavelength of TM to analyze the relation between snow reflectance and snow contaminants, and we come to the same conclusion as from the hyperspectral analysis. Therefore, this method can be used in combination with TM image to forecast the contaminants in snow.
Key words： hyperspectral remote sensing; snow reflectivity; snow contaminants; TM
