The Field Spectral Measurements Program of the Canada Centre for Remote Sensing

SUMMARYA mobile spectroscopy laboratory has been set up at the Canada Centre for Remote Sensing to measure the spectral reflectances of targets of interest. The reflectometer can measure the radiances of multiple targets within the wavelength range from 0.3 to 13.0 μm with a wavelength resolution of 0.025 μm between 0.3 and 1.0 μm, 0.005 μm between 1.0 and 2.5 μm and 2% of the measured wavelength between 3.0 and 13.0 μm. The radiance data is calibrated to reflectances by observing at each wavelength, the incoming solar energy about 20 msec before the radiance measurements of the targets commence. These data are stored upon digital cassette tapes which are later analysed on a computer system in the laboratory. This paper describes the instrumentation, the data procedures and analysis software.
