  1. Particle number measured by a TSI 3775 condensation particle counter (particle diameters, Dp>4 nm); non-volatile particle number measured by a TSI 3022 condensation particle counter (Dp>7 nm); cloud condensation nuclei (CCN) number concentration at (2.6±0.2)% supersaturation measured by a DMT CCN counter; black-carbon-equivalent (BC-equiv.) particle mass measured by a Thermo Multi-Angle Absorption Photometer (MAAP); particle volume measured by a TSI Engine Exhaust Particle Sizer (EEPS) (5.6 nm>Dp>560 nm). Emissions indices reported as the geometric mean ⋇ 1 geometric standard deviation (g.s.d). Note that kg−1 denotes ‘per kilogram of fuel’.
