Paper Abstract

The processes used to calibrate a field spectroradiometer are described. The spectro-radiometer uses four CVF's and four detectors with two of each in two separate instruments. Wavelength calibration procedure was to illuminate the aperture of the spectroradiometer with energy containing spectral lines at known wavelengths, and to note the linearity of the wavelength signal over the range of the spectral lines. Spectral radiance calibration consisted of comparing analog signals from the detectors to calibrated external references under known conditions.
