Kurzfassung
Optical remote sensing and Earth observation instruments rely on precise radiometric calibrations which are generally provided by the broadband emission from large-aperture integrating spheres. The link between the integrating sphere radiance and an SI-traceable radiance standard is made by spectroradiometer measurements. In this talk, the calibration efforts of a Spectra Vista Corporation (SVC) HR-1024i spectroradiometer are shown and how these enable radiance transfer measurements at the Calibration Home Base (CHB) for imaging spectrometers at the Remote Sensing Technology Institute (IMF) of the German Aerospace Center (DLR). Using this calibrated spectroradiometer, radiance transfer measurements are performed with relative expanded uncertainties between 1% and 3% (k = 2) over the wavelength range from 380 nm to 2500 nm, which are limited by the uncertainties of the applied radiance standard.
