Size-Resolved Aerosol Mass and Aerosol Number Distributions Encountered During The NCAS Trans-Atlantic Saharan Dust AERosol and Ocean Science Expedition (AEROSE) 2004
Abstract
In-situ measurements of size-fractionated aerosol mass and aerosol number density distributions were performed during the NCAS Trans-Atlantic Saharan Dust AERosol and Ocean Science Expedition (AEROSE) 2004. This was a 27 day mission aboard the NOAA Ship Ronald H. Brown (RHB). The cruise tracks for AEROSE 2004 coincided with the climatological Saharan Dust storm belt (5o N to 14o N and 60o W to 19o W) between the Caribbean Lesser Antilles and the west coast of Africa. A Quartz Crystal Microbalance Cascade Impactor (QCM) and a Laser Particle Counter (LPC) were used to retrieve the mass and number distributions. Each instrument is designed to make size-resolved measurements in six size fractions. The range for the QCM is from 5.0 microns to 0.15 microns. The range for the LPC is from 25 microns to 0.3 microns. I will present the evolution of size-resolved aerosol mass distribution and aerosol number distributions during a case study dust storm event.
