The presence of volatile organic compounds (VOCs), which include hydrocarbons, monoterpenes and oxygenates, in the atmosphere has become important to climate
We are developing a method for accurately quantifying greenhouse gas emissions from natural and anthropogenic sources and sinks to meet the requirements for
Extreme events test buildings and infrastructure in ways and on a scale that cannot be easily replicated in a laboratory – buildings and infrastructure are
The goal of this project is to extend and improve the measurements of the key climate record of the long-term balance between Earth absorption of solar energy
The Field Strength Metrology Project develops measurements of free-space electromagnetic (EM) emissions to help evaluate electronic interference of electronic
The National Institute of Standards and Technology (NIST) has developed and maintains evaluated libraries of reference data for the identification of chemicals
The metabolomics program at NIST is a collaboration between multiple institutions located at the Hollings Marine Laboratory (HML) in Charleston, SC. This
Rather than relying on templates, processing complex metrology data can be automated to reduce both the time required and the potential for transcription and
As a result of the environmental impact of mercury and the neurotoxic risk associated with trophic transfer of methyl mercury to humans, the reduction of
Optical frequency combs convert a laser source containing a single frequency of light into pulses that include thousands of frequencies. This project aims to
In response to worldwide initiatives to phase down working fluids that have a high global warming potential if accidentally released, the refrigeration and air
NMR spectroscopy is routinely used to analyze chemical mixtures in the liquid phase. It is far less common for these techniques to be applied to vapor-phase
The NIST Headquarters in Gaithersburg, MD also provides a convenient testbed to evaluate the current state of knowledge relating optical remote sensing to
Radio-frequency (RF) waves and microwaves are involved with almost every facet of everyday life. Radio stations, television, wireless devices, satellite
NOAA's Chemical Science Laboratory and NIST's Greenhouse Gas Measurement Program are working collaboratively to develop and maintain a new Department of
The Organic Chemical Metrology Program exists within the Chemical Sciences Division, MML, which is located at the Hollings Marine Laboratory in Charleston, SC.
The Wildland-Urban Interface (WUI) is defined as the location where structures and communities meet or intermingle with undeveloped wildland. In the U.S., over
The Indianapolis urban testbed began in 2010 as the Indianapolis Flux Experiment, or INFLUX. INFLUX was designed to verify top-down methods for estimating
Three separate interlaboratory comparison exercises for environmental contaminants in marine specimens were administered in 2007/2008 by the Chemical Sciences
To support urban greenhouse gas (GHG) measurement capability, NIST is developing a low-cost sensor platform that can be deployed within existing measurement
LUnar Spectral Irradiance (LUSI) is a program to radiometrically characterize the Moon for use as an on-orbit reference standard suitable for satellite
Because of the complexity of microbial communities, we are working to develop measurements that will enable more reproducible design and control over of such
For the past 40 years NIST has developed SRMs for the determination of inorganic and organic contaminants in environmental matrices such as sediments/soils
The Biochemical and Exposure Science Group at the Hollings Marine Laboratory tests and optimizes methods to accurately and precisely measure environmental
