Fig1-needleleaf forest.txt contains all the observation data with each reference given for figure 1. The deposition velocity vd and diameter dp are shown in ordered arrays. vd_err and dp_err define the deposition velocity and diameter error bars. Fig 2-needleleaf.txt contains same observation data as Fig1-needleleaf forest.txt Fig3-Broadleaf forest.txt contains all the observation data with each reference given for broadleaf forests in Fig 3. Data format same as Fig1 Fig4-Grasst.txt contains all the observation data with each reference given for grass in Fig 4. Data format same as Fig1 Fig5.txt contains data from Zhang et al. 2014 for three different U* values Fig6-Watert.txt contains all the observation data with each reference given for water in Fig 6. Data format same as Fig1 DataFig7,TXT is a tab-deliminated text file containing the data in tabular for for Figure 7 DataFig8,TXT is a tab-deliminated text file containing the data in tabular for for Figure 8 Fig14a-133_P6p3_add_newadd_PM25_TOT_126719_boxplot_hourly_data.csv is a CSV file containing data for the hourly average median and 1st and 3rd quartiles of observation and two 1.33 km model runs that are represented by boxes in figure 14a. Fig14b-12US1_P6p3_add_PM25_TOT_211556_boxplot_hourly_data.csvis a CSV file containing data for the hourly average median and 1st and 3rd quartiles of observation and two 12 km model runs that are represented by boxes in Figure 14b. Fig15-133_P6p3_add_newadd_PM25_TOT_728997_spatialplot_diff.csv is a CSV file containing all the data for the bias and error for NEW and BASE 1.33 km model runs and the differences in bias and error between the models at AQS sites Fig16-12US1_P6p3_add_PM25_TOT_971641_spatialplot_diff.csv is a CSV file containing all the data for the bias and error for NEW and BASE 12 km model runs and the differences in bias and error between the models at AQS sites Fig17-12US1_P6p3_add_PM25_TOT_104554_spatialplot_diff.csv is a CSV file containing all the data for the bias and error for NEW and BASE 12 km model runs and the differences in bias and error between the models at IMPROVE sites. Portions of this dataset are inaccessible because: Figs 9-13 are all plots directly from CMAQ output files which are far too large. They can be accessed through the following means: Can contact primary author, Jon Pleim, to access the data. Format: CMAQ netcdf output files
