Take-off engine particle emission indices for in-service aircraft at Los Angeles International Airport.

ABSTRACT: We present ground-based, advected aircraft engine emissions from flights taking off at Los Angeles International Airport. 275 discrete engine take-off plumes were observed on 18 and 25 May 2014 at a distance of 400 m downwind of the runway. CO₂ measurements are used to convert the aerosol data into plume-average emissions indices that are suitable for modelling aircraft emissions. Total and non-volatile particle number EIs are of order 10¹⁶-10¹⁷ kg^-1 and 10¹⁴-10¹⁶ kg^-1, respectively. Black-carbon-equivalent particle mass EIs vary between 175-941 mg kg^-1 (except for the GE GEnx engines at 46 mg kg^-1). Aircraft tail numbers recorded for each take-off event are used to incorporate aircraft- and
