Refractory black carbon (BC) nanoparticles grow from hot hydrocarbon gases emitted by the incomplete combustion of biomass and fossil fuel. These particles are transported on a hemispheric scale in the troposphere and are predominately removed by wet deposition. Black carbon particles convert solar-radiation into heat altering the thermal structure of the atmosphere. Warming air aloft BC particles also cool the atmosphere below increasing atmospheric stability resulting in  reduced  convective preicptation. While modeling studies suggest that BC has a large impact on precipitation BC wet deposition fluxes are poorly constrained. During 2019 we have been conducting an exploratory study of BC wet deposition using NADP standard operating procedures to investigate the feasiability of monitoring BC wet deposition in the NADP network. Preliminary results from the study suggest that BC can be stabilized as an aqueous colloid on time spans ranging from days to weeks with corse filtration, modification of pH and appropriate selection of sample containers. We will present results from study and outline the potential for collecting and archiving samples within the NADP network.
