The Clingmans Dome cloud water deposition estimates show an overall decline in sulfur and nitrogen deposition estimates over the history of the project despite interannual increases observed for both species in 2001, 2004, 2006, 2009, and 2011. Despite some annual variability, estimates of total deposition, i.e. deposition produced by cloud + dry components, show a general, overall decline since 1999 (Figure 6-1). Since 1999, total sulfur deposition decreased 80.1 percent and total nitrogen deposition decreased 64.5 percent. Total cloud water sulfur deposition has decreased 80.5 percent since 1999 with a 63.3 percent decrease in total cloud water nitrogen deposition. The 2011 seasonal estimates show that dry deposition is a small contributor to the deposition of pollutants at high elevations (Table 5-1). Cloud deposition is the significant pathway for deposition at these elevations.
