Remote Quantification of Stack Emissions from Marine Vessels

Paper in proceeding, 2016

Stationary and mobile (on-vessel) measurements of ship specific emission factors and total emission were carried out in the port of Los Angeles and Long Beach. The measurement techniques developed to characterize individual ship emissions were presented. The data were obtained with a zenith DOAS technique for NO 2 and "in-situ" sniffer technique for SO 2 , NO x , CO 2 , and particulates. The measured particle properties corresponded to particulate number, particulate mass, and black and organic carbon. Total emissions of NO 2 from the harbors were also obtained through mobile optical zenith sky measurements. The potential VOC emissions were investigated when fueling the ships and other VOC sources in the harbor using techniques like the Solar Occultation Flux technique. This is an abstract of a paper presented at the A & WMA's 109th Annual Conference & Exhibition (New Orleans, LA 6/20-23/2016).
