NIST s role in providing the optical radiation measurement science and standards to ensure the quality, accuracy, and comparability of our Nation s remote sensing measurements in support of climate-change research is presented. Climate research has particularly stringent measurement requirements because of the need to detect extremely small changes in the Earth s environment over long periods of time. Moreover, because climate research requires the integration of a large number of measurements performed by different sensors, the measurements need to be tied to international standards to allow comparisons to be made independently of instrument, organization, or deploying nation. In aiding climate change research, NIST provides irradiance, radiance, and reflectance standards, deploys instruments to validate radiometric scales for satellite programs, and leads measurement intercomparisons. NIST also researches new approaches for calibrating remote sensing instruments to provide improved spectral, spatial, and temporal characterization and calibration. Such research has led to novel laser, LED, and micro-mirror technology for generating optical radiation standards. NIST is also strengthening its partnerships with other organizations and government agencies, including NOAA, to help address the many measurement challenges associated with climate change research.
