The Vacuum Infrared Hyperspectral Radiance Temperature Standard Facility for Infrared Hyperspectral radiance calibration was established at National Institute of Metrology for calibrating the radiance temperature of infrared remote sensing payloads. The state-of-the art of the system was introduced, such as, the structure, the new designed standard blackbody, the calibration method and the traceability. The vacuum reduced background chamber was built for the customer blackbodies. The standard blackbodies, including the variable temperature blackbodies and the fixed-point blackbodies, were designed. The radiance temperature of the customer blackbodies were calibrated by the standard blackbodies through a Fourier transform infrared spectrometer. The temperature range of the new designed standard blackbody was from 125 K to 500 K with a 30 mm in diameter and 0.999 7 emissivity of the cavity. The radiance temperature standard uncertainty of the blackbody was better than 0.026 K@300 K/10 m. The fixed point blackbodies included a mercury blackbody, a gallium blackbody and an Indium blackbody. The cavities diameter were all 25 mm, and the uncertainty of the fixed blackbodies was better than 0.020 K@300 K. The system could support the requirements of lots of infrared remote sensing payloads. This facility can provide the radiance temperature tracebility for most infrared remote sounders with low uncertanty, high sprectral resolution and strong extensibility.

Abstract: The Vacuum Infrared Hyperspectral Radiance Temperature Standard Facility for Infrared Hyperspectral radiance calibration was established at National Institute of Metrology for calibrating the radiance temperature of infrared remote sensing payloads. The state-of-the art of the system was introduced, such as, the structure, the new designed standard blackbody, the calibration method and the traceability. The vacuum reduced background chamber was built for the customer blackbodies. The standard blackbodies, including the variable temperature blackbodies and the fixed-point blackbodies, were designed. The radiance temperature of the customer blackbodies were calibrated by the standard blackbodies through a Fourier transform infrared spectrometer. The temperature range of the new designed standard blackbody was from 125 K to 500 K with a 30 mm in diameter and 0.999 7 emissivity of the cavity.
