Primary Realization of Both Spectral Radiance and Reflectance in the Mid- and Far-Infrared for Climate Change Science Support

摘要

Long term absolute measurements of the Earth spectral radiance in the infrared are essential for climate change modelling and prediction. Proposed climate science missions, such as CLARREO, along with weather sounders, require rigorous pre-flight radiometric calibration, as well as validation of techniques for maintaining traceability to fundamental units in space. This paper provides an update on recent progress in the area of thermal emission metrology standards at NIST, and discusses the techniques and instrumentation under development, which may help to achieve "climate benchmark" data quality for future space missions, as well as support other applications.
