Abstract
A series of field studies was designed to examine the ionic composition of aerosol particles at several locations in the Interagency Monitoring of PROtected Visual Environments (IMPROVE) network, to address some of the issues. Study sites included Bondville, Illinois, San Gorgonio Wilderness, California and New Jersey. Complementary measurements were conducted using a MOUDI impactor to examine aerosol species size distribution. The results show that nitrate is sometimes present as fine particle ammonium nitrate but at other times is dominated by coarse mode sodium or calcium nitrate. The results also demonstrate that significant loss of ammonium occurs off nylon filters in conditions studied.
