Abstract

The NASA GSFC Code 618 Calibration Laboratory maintains instruments and National Institute of Standards and Technology (NIST) traceable calibrated sources and detectors to calibrate, characterize, and monitor remote sensing instrumentation throughout NASA and the larger scientific community. Under the Calibration Laboratory umbrella, we operate the Radiometric Calibration Lab (RCL) focused on calibrating instrument radiometers, the Diffuser Calibration Lab (DCL) specializing in NIST traceable calibration of reflective and transmissive space diffusers. The RCL uses broadband sources as well as an array of options for monochromatic spectral calibration to provide regular NIST traceable calibration services to ground, flight, and remote sensing missions at NASA GSFC. The DCL uses scatterometers to measure the Bidirectional Reflectance and Transmittance Distribution Functions (BRDF & BTDF) of flight diffusers and witness samples. As we look to the future, the Calibration Laboratory will be automating routine processes throughout the facility and updating our online data collection and distribution capabilities. We are adding monitoring radiometers to our Grande calibration sphere to improve NIST traceability. Hardware updates to our scatterometers will keep us aligned with the diffuser calibration capabilities being developed at NIST.
