Environment/Climate Portal - Overview Through its partnerships with industry, government, and academia, NIST is helping to advance measurements and tools for environmental science, for example by calibrating the sensors of climate-mapping satellites and detecting ever more minute quantities of toxins and pollutants in our air, soil, water, and blood. Programs and Projects
Pipeline-Scale Flow Measurement Standards for Natural Gas
NIST is developing gas flow calibration tools known as critical flow venturis (CFV), or sonic nozzles, to calibrate natural gas flow meters used … more
Aperture area measurements
Radiometric and photometric measurements require defining apertures. The accuracy to which these measurements can be accomplished requires … more
NIST Intercomparison Exercise Program for Organic Contaminants in the Marine Environment
Since the beginning of the National Oceanic and Atmospheric Administration (NOAA) National Status and Trends (NS&T) Program in 1987, NIST … more
Synchrotron Radiation-Based Calibrations for Space Weather Prediction
Orbital ultraviolet and extreme-ultraviolet spectrometers are calibrated on beamline 2, taking advantage of the calculability of synchrotron … more
