having a monitor on the ground to track emissions downwind from a facility, and putting instruments in a van and driving around. Hodshire is testing these methods here in Colorado, but there are many across the country that are also testing other methods....
Emissions Analytics is the leading independent global testing and data specialist for the scientific measurement of real-world emissions.
Results from single-blind testing assess performance for detection and localization for all methods, and quantification for some methods. When the test protocol and operational model are well matched, we found that results provide good insight to the performance of technologies. However, the wide ...
The US has slashed smog-causing pollutants such as airborne sulfur dioxide in the past 20 years, but the cuts have unintentionally increased ground and water pollution in some local areas, according to research from Princeton and Colorado State University. In an open-access paper in the journal ...
Composition of Light-Duty Motor Vehicle Exhaust Particulate Matter in the Denver, Colorado Area A study to characterize particulate matter emissions from 195 in-use gasoline and diesel passenger vehicles was conducted during the summer of 1996 and the......
This report consolidates results from a number of emission testing programs on in-use passenger cars. Vehicles from the 1975 through 1981 model years were ... Jones, G. T 被引量: 1发表: 1981年 REDUCTION OF EMISSIONS FROM A HIGH SPEED FERRY Emissions from marine vessels are being scrutinized...
A company in Boulder, Colorado has produced a camera-and-AI-based technology that can recognize ea-gles and other birds as they approach in enough time to shut off turbines in their flight paths. Their tool,called IdentiFlight, can detect 5.62 times more bird flights than human observers ...

Soil emissions of nitrous oxide contribute substantially to global warming from agriculture. Spatiotemporal variation in nitrous oxide emissions within agricultural fields leads to uncertainty in the benefits of climate-smart agricultural practices. Here
Several viable but conflicting explanations have been proposed to explain the recent ~8 p.p.b. per year increase in atmospheric methane after 2006, equivalent to net emissions increase of ~25 Tg CH4 per year. A concurrent increase in atmospheric et
