Table 4: Average (with standard deviation) and median (with 25th and 75th quartiles) values are reported for deposition velocities, fluxes, concentrations, and normalized deposition velocities for each site, separating PM2.5 from particle number data. In this table data is selected for unstable atmospheric stability cases (including quasi-neutral cases).
