This describes the contents of the Supplemental Data file for Porter et al. (2018), "Eddy flux measurements of sulfur dioxide deposition to the sea surface". 

The Supplemental Data file is a comma delimited text file containing data used in the calculation of air/sea fluxes and transfer velocities for the field campaign at Scripps Pier in 2014. Only data passing quality control is listed.  The data set includes every variable in equations 16-19 in the manuscript.  This includes, fluxes, air/sea differentials and transfer velocities for water vapor, sensible heat, sulfur dioxide and momentum fluxes.  Air density is also included where appropriate.  

The parameters (column headers) and units in the data file are:

[DOY]: Decimal day of year (Days after Jan 1 00:00).

[H2O_Flux]: Water vapor flux (mol/m2/s).

[Delta Q]: Difference between dry air mixing ratio of water vapor measured at 10m above the sea surface and theoretical dry air mixing ratio at the saturation vapor presssure at the measured sea surface temperature (mol/mol dry air).

[Dry_Air_Density]: Moles of dry air per cubic meter (mol/m3).  Used in Equation 17.

[k_H2O]: water vapor transfer velocity (m/s).

[Heat_Flux]: Sensible heat flux (W/m2).

[Delta_temp]: Temperature differential between the air at 10m and the sea surface (deg C). Used in Equation 19.

[Air_Density_sh]: Air density (kg/m3). Used  in equation 19.

[k_SH]: Sensible heat transfer velocity (m/s).

[SO2_Flux]: Sulfur dioxide flux (mol/m2/s).

[SO2_conc]: Sulfur dioxide concentration (mol/m3).

[k_SO2]: Sulfur dioxide transfer velocity (m/s).

[Mom_Flux]: Momemtum flux (N/m2).

[U10]: Wind speed at 10m above the sea surface for neutral atmospheric conditions (m/s).

[Air_Density_mom]: Air density (kg/m3).  Used in equation 18.

[k_mom]: Momentum transfer velocities (m/s).
