NIST Ocean Carbon Measurements

Ongoing
NIST is committed to sustaining the quality of ocean carbon measurements by developing capabilities to provide certified reference materials for the ocean carbonate system measurements and by conducting research to understand fundamental elements of the ocean carbon thermodynamic system. NIST Ocean

The NIST Standard Reference Photometer for Ozone Measurement Traceability

Ongoing
The concentration of ozone in the atmosphere continues to be an important global issue both scientifically and politically. Stratospheric ozone protects the Earth from harmful UV radiation, while tropospheric ozoneis a major health concern and contributes to global climate change as a greenhouse gas

Northeast Corridor Urban Test Bed for Greenhouse Gas Emissions

Ongoing
The NEC project includes multiple measurement and analysis components. The backbone of the NEC project is a network of in-situ CO2 and CH4 observation stations with continuous high-accuracy mole fraction measurements of these two greenhouse gases. In addition, the University of Maryland, Stony Brook

Performance Metrics for Industrial Gas Separation and Purification

Ongoing
Sorbents in Direct Air Capture (DAC) are exposed to the atmosphere, where they adsorb CO2 then are isolated from atmosphere, the CO2 is driven off by heating or pulling vacuum, refreshing the sorbents. This adsorption-refresh cycle depends not only on the competitive adsorption of CO2 with the other

Smoke Stack Flow Measurement

Completed
The Fluid Metrology Group is using its smoke stack simulator (See Fig. 1.) and field tests in operating smoke stacks to critically test conventional and improved ways of measuring the flow of stack gases. In the NIST stack simulator, the inlet cone and reference (upstream) section of the simulator
