Fluxes of Saharan dust deposition across the tropical North Atlantic Ocean

Dataset includes sediment-trap data of Saharan dust deposition along a trans-Atlantic transect at 12°N, Model simulations of dry- and wet deposited dust across the same transect, and satellite observations of Dust Optical Depth (DOD) and precipitation.

Fig. 2 includes dust deposition fluxes for sampling years 2013 and 2014, precipitation obtained from TRMM (Tropical Rainfall Measuring Mission) at 1x1° resolution, and DOD calculated from Aerosol Optical Depth (AOD) from MODIS (Moderate Resolution Imaging Spectroradiometer) Collection 6 data also at 1x1° resolution.

Fig. 3 shows the monthly averages of dust deposition fluxes (average for 2013 and 2014 sampling years), dust concentrations obtained at the monitoring station at Barbados (13.2°N, 59.4°W) averaged for 2013-2014, model simulations of dry and wet dust deposition using the Community Earth System Model (CESM), at 5°x10° resolution, between 10 and 15°N and 10 and 60°W, and averaged monthly precipitation at the sediment-trap sites (1x1° resolution) from TRMM for 2013-2014 sampling years.
