The longest continuous precipitation monitoring operation in Florida has occurred at a site located on the University of Central Florida (UCF) campus located near Orlando from 1977 to the present. One site at the Kennedy Space Center and four other sites in Florida and three sites in Georgia have operated continuously since 1984 or earlier. Major ion concentrations including acidity vary considerably among sites and the UCF site exhibits higher acidity and nitrate concentrations than any other site. In general concentrations decrease as site location in moved from north to south except where site proximity to the ocean is a dominant factor. Nitrate has trended higher during the sixteen year period and acidity at UCF trended lower early in the sixteen year period but has trended toward higher concentrations when recent data are evaluated. When NO{sub x} and SO{sub 2} emissions from eastern and southeastern states and precipitation composition data for the period 1978--1988 are evaluated, there is no strong indication of relationships between emission and concentration or emission and deposition.
