Longitude-pressure cross-sections of MERRA-2 total and speciated (sea salt, SO42−, black carbon, organic carbon, and dust) aerosol mass mixing ratios (μg m−3 Standard Temperature and Pressure [STP]) at a latitude of 32°N. Values represent the seasonal average for June, July, and August (JJA) between 2014 and 2018. Black vertical lines are representative of the longitudinal boundaries (60°–85°W) of the Western North Atlantic Ocean (WNAO) region as defined in this work. The white areas represent the topography diagnosed from local surface pressure.
