Abstract
The observational datasets were gathered at the Rosenstiel School of Marine and Atmospheric Science in Miami, Florida. These support the analysis described within Kramer et al., 2020, doi:10.5194/acp-2020-1. The protocol for the bulk surface dust mass concentrations is described further in Zuidema et al., 2019, Bulletin of the American Meteorological Society (https://doi.org/10.1175/BAMS-D-18-0083.1). The data contributing to the individual figures are described in more detail below, including their format. Major soluble inorganic ions from July and August of 2014 extracted from Whatman-41 filters sampling under pumped high-flow conditions; size-resolved surface dust mass concentrations collected by a high volume cascade impactor on 17 days from July-September 2016; micro pulse lidar depolarization ratio vertical profiles from May-September of 2014, 2015 and 2016; sun-photometer-derived aerosol optical depths from the same time period; and GEOS-5 (Goddard Earth Observing System Model Version 5) dust and total aerosol extinctions for May-August of 2014, 2015, and 2016.

DESCRIPTION OF DATA CONTRIBUTING TO THE INDIVIDUAL FIGURES:
Fig. 1: The csv file 'MIA14RWT_paper.csv' (KramerEtAl_2020_dust_and_inorganics.zip) includes the July-August 2014 daily-resolved (approximately) concentrations of chlorine (column 25 "CL Air"), sodium (column 44, "Na air"), nitrate (column 31, "NO3 air" ), sulfate (column 37, "SO4 air") and non-sea-salt sulfate (column 46,NssSO4), potassium (column 52, "K Air") and calcium (column 58, "Ca Air"). These concentrations were derived using flame atomic absorption to determine sodium and suppressed ion chromatography to determine chloride, nitrate and sulfate, following the protocol of Savoie et al., (1989). Dust concentrations are also included (column 63, 'Ash air'). These are derived from filter measurements detailed further in Zuidema et al., (2019), and should be multiplied by 1.3 before use. Note the dust mass concentrations used throughout this paper are those distributed through Zuidema et al., 2019. File Creator: Samantha Kramer and Lillian Custals.
Fig. 2: The Excel file 'MIACascadeImpactor2016final_paper.xls' (KramerEtAl_2020_dust_and_inorganics.zip) contains the high-volume cascade impactor (manufacturer: Tisch) filter dust mass concentrations for 20 July-2September, 2016 (column 36, 'Dust Ash*1.3'). The impactor discriminates for particle aerodynamic diameters of 2.1, 4.2 and 10.2 microns, with one final plate captured the remaining smaller sizes. The impactor was located next to the filter sampling site, with the protocol following Li-Jones and Prospero (1998). File Creator: Samantha Kramer and Lillian Custals.
Fig. 3: Micro Pulse Lidar (MPL) linear depolarization ratios for June-September of 2014, 2015 and 2016 are available from daily text files named 'DepolRatio_[year]-[month]-[day].txt', contained within monthly tar files '[year]-[month].tar', where month=[06,07,08,09] (KramerEtAl_2020_lidar.zip). This lidar was situated within an air-conditioned penthouse on top of the Marine Science Center of the Rosenstiel School. File Creator: Rodrigo Delgadillo
The bulk dust mass concentrations are available from DOI: https://doi.org/10.17604/q3vf-8m31 (see comment below) in both Excel and netcdf files. A data discrepancy was uncovered, in which the data from the early years within the Excel file are not always at a daily time resolution. The data within the netcdf file is at a daily time resolution throughout.

The GEOS-5 FP aerosol optical depths are available from netcdf files 'goes5fp_miami_aop_ext532nm.[year][month].nc4', with year=[2014,2015,2016] and month=[06,07,08,09] (KramerEtAl_2020_geos5fp.zip). File Creator: Ravi Govindaraju
The AERONET aerosol optical depth values are publicly-available from aeronet.gsfc.nasa.gov, and are also available here from csv files '15_Master_DM_AOD_lev15_2.csv' and '16_Master_DM_AOD_lev15_2.csv' (KramerEtAl_2020_dust_and_inorganics.zip). These correspond to the 'Key_Biscayne' and 'Key_Biscayne2' sun photometers, Level 1.5, version 2. The AERONET sun photometers are located near the MPL. File Creator: Samantha Kramer
