IMPROVE Coarse Mass Speciation Study

Background

To more fully investigate the composition of coarse particles, a program of coarse particle sampling and speciation analysis at nine of the IMPROVE sites was initiated between 19 March 2003 and 23 December 2003, with each site operating for one year. Sites were selected to be representative of the continental United States and were operated according to IMPROVE protocol analytic procedures.
