PM Source Apportionment
CARB funded Professor Phil Hopke at Clarkson University to conduct a PM
source apportionment analysis of STN and IMPROVE data on the West Coast
using receptor modeling methods to reconcile with source-oriented model
results. Professor Hopke used the positive matrix factorization method
and PM composition data to assess the contribution of ship
emission to ambient PM concentration at a number of coastal stations.
This project was complete in October 2006.
