Extended Data Table 1 | Primary PM2.5, NOx and SOx emissions totals for 2005, 2011 and 2018
Emissions expressed in teragrams per year for each sector for 2005, 2011 and 2018. Emissions for all sectors apart from aviation are derived from EPA’s NEI. Aviation emissions are taken from
the AEDT inventory^29 (for years 2006, 2010/2012 and 2015) and include emissions that occurred over the contiguous US. The percentages of aviation emissions that occur within around 1 km of
altitude (landing and take-off emissions) are given in parentheses, and are the aviations emissions included in our analysis.
