PMEL's Atmospheric Chemistry Group (ACG) and U.S. Department of Energy's Pacific Northwest National Laboratory (PNNL) are working together to deploy the first of an autonomous system to observe atmospheric, cloud, and aerosol properties on a commercial ship called BEACONS (Boundary Layer Exploration of Aerosols and Clouds ON Ships).

The 6-month pilot project is scheduled to begin as early as May. ACG will take measurements of aerosol properties relevant to radiative forcing including the particle number size distribution, total particle number concentration, and aerosol light scattering and absorption coefficients. Measurements will be collected by the Modular Sampling Platform (MSP, pictured) developed by ACG at PMEL. The MSP will be stationed atop the flybridge forward of the stack on the commercial ship "Marjorie C" which transits regularly between San Diego and Hawaii. The ACG and PNNL measurements will be used to develop an unattended system for aerosol and cloud data collection to improve model prediction.
