Long‐term atmospheric NOx/CO enhancement ratios in megacities provide evaluations of
emission inventories. A fuel‐based emission inventory approach that diverges from …

To investigate changes in the ozone (O 3) chemical production regime over the contiguous
United States (CONUS) with accurate knowledge of concentrations of its precursors, we …

National emission inventories (NEIs) take years to assemble, but they can become outdated
quickly, especially for time-sensitive applications such as air quality forecasting. This study …

Fossil-fuel CO 2 emissions and their trends in eight US megacities during 2006–2017 are
inferred by combining satellite-derived NO X emissions with bottom-up city-specific NO X-to …

Accurate emission inventories and their temporal trends must be incorporated into pollutant
inventories to allow for reliable modeling of the country's past, present, and future air quality …

Abstract Nitrogen oxides (NOx= NO+ NO2) are produced during combustion processes and,
thus may serve as a proxy for fossil fuel‐based energy usage and coemitted greenhouse …

Emission inventory development for air pollutants, by compiling records from individual
emission sources, takes many years and involves extensive multi-national effort. A …

Nitrogen oxides (NO x) play a central role in catalyzing tropospheric ozone formation.
Nitrogen dioxide (NO2) has recently reemerged as a key target for air pollution control …

We illustrate the nonlinear relationships among anthropogenic NO x emissions, NO 2
tropospheric vertical column densities (TVCDs), and NO 2 surface concentrations using …

There are many isolated sources of NOx emissions across the western United States,
including electrical power generation plants and urban areas. In this manuscript, two …
