When Super Bowl LVI kicks off at the SoFi Stadium in Los Angeles on February 13, a nearby command center operated by emergency managers will include NOAA experts.
A new NOAA-led study of precipitation high in the Colorado Rockies aims to give water managers better forecasts for runoff in the critically important Colorado River Basin.
When COVID-19 pandemic began in the US, counties and cities across the nation imposed stay at home orders, closed schools or imposed travel restrictions. From March 2020 onward, many Americans hung up car keys and settled into their homes for work and school. Traffic patterns dramatically changed, and previously smog filled vistas became clearer.
NOAA and NIST have installed a Doppler lidar instrument to an existing weather station on top of the Department of Commerce’s Herbert Clark Hoover Building in Washington, D.C. to measure wind flow and turbulence in the lowest part of the atmosphere for a research project studying greenhouse gas emissions in the Capitol area.
Running on the newest version of NOAA’s Global Forecast System, or GFS, the FV3-Chem model forecasts the distribution of some primary air pollutants: smoke, soot, organic carbon, sulfate, and large and small particles of dust and sea salt - collectively known as aerosols. Because these aerosols affect the weather, the model also provides weather forecasts.
People living in the American Southwest have experienced a dramatic increase in windblown dust storms in the last two decades, likely driven by large-scale changes in sea surface temperature in the Pacific Ocean drying the region’s soil, according to new NOAA-led research.
From our nation’s founding, the Fourth of July has been synonymous with fireworks. While many grew up learning that fireworks can be dangerous to the eyes and hands if not handled properly, fireworks also produce air pollutants, including particulate matter, that are linked to short-term or long-term health effects.
NOAA has authored a new study appearing in the journal Atmospheric Environment that quantifies the surge in fine particulate matter – particles that are two and one half microns in diameter (PM2.5) – on July 4, using observations from the 315 U.S. air quality monitoring sites that operated from 1999 to 2013. The new study is the first nationwide quantitative analysis of the effects.
A perspective from NOAA and NASA scientists published online on January 29, 2014 in Nature Climate Change addresses a key question surrounding proposals to engineer the Earth’s climate to increase the planet’s reflection of sunlight to counteract climate warming: Could we measure manmade increases in reflectivity?
