ATIs Model A23-14 is a portable generator designed to produce an ozone gas concentration below 1 PPM, which can be used for detector calibration at almost any location.
While much of the world has experienced a warmer climate in recent years, the U.S. Southeast has cooled. Scientists want to know why because the answer could reveal keys to improving air quality and understanding climate change. To study the cooling Southeast, scientists at several institutions have joined forces to conduct the Southern Atmosphere Study (SAS), the largest study on southeastern U.S. air quality since the 1990s. These include the U.S. Environmental Protection Agency, National Center for Atmospheric Research, National Science Foundation, National Oceanic and Atmospheric Administration and the Electric Power Research Institute. Five air quality studies fall under the SAS umbrella.Read More
Researchers at Washington State University will quantify uncombusted methane emissions throughout the U.S., according to a release . The investigators will look at emissions from local gas systems and try to estimate a national emissions rate. Uncombusted natural gas is more harmful to the atmosphere than carbon dioxide because it has a higher warming potential. Emissions of uncombusted methane along the natural gas supply line haven’t been measured on a national scale and studying them will become more important as the U.S. natural gas industry continues to expand. The Washington State study begins in April and is funded by major natural gas utilities, the Environmental Defense Fund and Conestoga-Rovers and Associates, an environmental engineering and consulting firm.Read More
A new air monitoring vehicle was recently delivered to the city of Vancouver with praise and skepticism from metropolitan residents, according to The Province. The vehicle, known as the Mobile Air Monitoring Unit, is loaded with sensors which will monitor air quality. The city wants to monitor particulates in the air from coal, diesel and oil tankers. Data collected by the truck transmits to the city hall. Some citizens are happy to have a new mobile air monitoring station that will supplement the city’s 26 stationary monitoring stations. However, many citizens criticized the loaded Ford F-450’s price tag of more than $280,000.Read More
