Assessment of air quality has been traditionally conducted by ground based monitoring, and
more recently by manned aircrafts and satellites. However, performing fast, comprehensive …

Pollutant emissions need to be accurately estimated to ensure that air quality plans are
designed and implemented appropriately. Emission factors (EFs) are empirical functional …

Abstract The 1999 Regional Haze Rule provides a context for this review of visibility, the
science that describes it, and the use of that science in regulatory guidance. The scientific …

Marine vessel inventories demonstrate that ship emissions cannot be neglected in
assessing environmental impacts of air pollution, although significant uncertainty in these …

We present geographically resolved global inventories of nitrogen and sulfur emissions from
international maritime transport for use in global atmospheric models. Current inventories of …

Road transport is often the main source of air pollution in urban areas, and there is an
increasing need to estimate its contribution precisely so that pollution-reduction measures …

For the 119 species of marine mammals, as well as for some other aquatic animals, sound is
the primary means of learning about the environment and of communicating, navigating, and …

Diesel-powered road vehicles are important sources for nitrogen oxide (NO x) emissions,
and the European passenger fleet is highly dieselised, which has resulted in many …

This paper reports on the analysis of on-road vehicle speed, emission, and fuel consumption
data collected by four instrumented vehicles. Time-, distance-, and fuel-based average fuel …

The emission rates for 221 vapor-phase, semivolatile, and particle-phase organic
compounds from motor vehicles plus fine particulate matter mass and some inorganic …
