Introduction

This supplementary table (2012JF002375R-ts01) contains original data and some basic statistical analysis of the  original data for vegetation, wind, threshold shear velocity, and horizontal mass flux for each of the 65 BSNE sites that we measured in the field. For the basic statistics, we computed mean, median, and standard deviation for unvegetated gap, plant canopy height, and scaled gap (gap/canopy height), and for windspeed, we computed mean, median, and maximum values. It is in Microsoft Word (.doc) format.

1. Characteristics of the primary model inputs, field measured total horizontal mass flux (Qt,act), and the errors of the horizontal mass flux estimation for all sites used in this study
1.1. Column #1: "Site #", unitless, simplified site name for each of the wind erosion monitoring sites. More description of the sites are found in the notation of the table.
1.2. Column #2: "Unvegetated gap", meters, including three sub-columns of mean, median, and standard deviation of unvegetated gap.
1.3. Column #3: "Plant canopy height", meters, including three sub-columns of mean, median, and standard deviation of plant canopy height.
1.4. Column #4: "Scaled gap", unitless, including three sub-columns of mean, median and standard deviation of scaled gap. The scaled gap was calculated by dividing each gap by the canopy height next to the gap.
1.5. Column #5: "u*t", threshold shear velocity for surface soil, m s-1, u*t was measured in the field.
1.6. Column #6: "FG", fractional cover of vegetation, unitless, measured in the field using the transect method.
1.7. Column #7: "Windspeed", m s-1, including three sub-columns of mean, median and maximum windspeed recoded in the wind tower located close to the field study sites.
1.8. Column #8: "Qt,act", g m-1 day-1, total horizontal mass flux as measured by the BSNE method. 
1.9. Column #9: "r2 of q(z) fitting", unitless, regression coefficient of measured time-averaged horizontal mass flux to a empirical equation (Equation 1 in the original paper).
