How are Oxides of Nitrogen (NOx) defined in the NEI?
For all source categories, NOx is compiled from emissions measurements that express NOx mass based on the molecular weight of nitrogen dioxide (NO2), which is 46. Even though emission streams initially consist mainly of NO from most sources, this expression of NOx by NO2 MW is appropriate due to the…

How are emissions trends compiled?
For criteria air pollutants and precursors, the emissions trends are based on the triennial National Emissions Inventory data, with some interim year data included for non-triennial years. The methods and interim-year approaches are described on the “Development of Data” tab included with the data provided on the Air Pollutant Emissions…
