Welcome to: ENVIRONMENTAL METROLOGY NIST's Support of Remote Sensing Radiometry The Environmental Metrology Project at NIST is a response to the critical needs of the U.S. Global Climate Change Research Program for accurate radiometric calibration of optical sensors. From the ultraviolet to the thermal infrared, quantitative measurements of the radiant flux incident, emitted, scattered, and reflected from the Earth and its environment can be used to determine physical parameters required for scientific research, global warning models, and ultimately, environmental policy decisions. The Optical Technology Division at NIST, with the support of NASA, NOAA, USDA, and EPA, is assisting in verifying these measurements by direct interaction with the various programs. Specialized transfer radiometers, field-deployable sources, round-robin activities, and measurement intercomparisons have been developed. In some cases, the facilities at NIST have been expanded.
