N2 - A cross-calibration radiometer covering the 400- to 900-nm range with a silicon "trap" detector has been designed and built. The radiometer was designed for comparing the output of preflight radiometric calibration sources for the MODIS and ASTER Eos sensors. These sources will be large aperture spherical-integrating sources with tungsten-halogen-bulb internal illumination. The two spheres will be calibrated using standards from NIST and NRLM. The radiometer is intended to compare the output of the spheres at seven wavelengths corresponding to MODIS bands, some of which overlap ASTER bands. The wavelength selection is by highly blocked nominal 10- to 15-nm-wide interference filters. The radiometer detectors, apertures, and filters are held at a controlled temperature slightly above ambient. The design and calibration of the radiometer are described.
