Table 48.2 Comparison of observed and modeled annual total wet deposition. Annual totals were
computed at each station and then spatially averaged across all sites for observations and each
simulation. The median and range of these values across models is shown for each AQMEII phase.

Fig. 48.1 Distribution of modeled annual total ozone dry deposition fluxes across all land cells. The
lines and vertical numbers above each box indicate the median of the distributions while the boxes
indicate the interquartile range. Each box represents a different simulation with “AQ1”, “AQ2”,
and “AQ3” denoting the three phases of AQMEII and the remaining characters randomly labeling
individual simulations
