Monterey FD Vaccine Clinic-4/5/21-1652-PMD

Important! For Dead Doctors Don t Lie Use: 888-379-2552 Monterey FD Vaccine Clinic-4/5/21-1652-PMD A City of Monterey Fire Department is hosting a vaccination clinic on Wednesday to all eligible populations. This clinic is for Individuals age 50 and over, People with a high chance of exposure (specific industries: agriculture and food, education and childcare, emergency services), Individuals age 16 or older at higher risk (18 or older for this Moderna vaccine clinic). The clinic will be held at the Monterey Conference Center off Portola Plaza.  

Atmospheric aging enhances the ice nucleation ability of biomass-burning aerosol

Ice-nucleating particles (INPs) in biomass-burning aerosol (BBA) that affect cloud glaciation, microphysics, precipitation, and radiative forcing were recently found to be driven by the production of mineral phases. BBA experiences extensive chemical aging as the smoke plume dilutes, and we explored how this alters the ice activity of the smoke using simulated atmospheric aging of authentic BBA in a chamber reactor. Unexpectedly, atmospheric aging enhanced the ice activity for most types of fuels and aging schemes. The removal of organic carbon particle coatings that conceal the mineral-based ice-active sites by evaporation or oxidation then dissolution can increase the ice activity by greater than an order of magnitude. This represents a different framework for the evolution of INPs from biomass burning where BBA becomes more ice active as it dilutes and ages, making a larger contribution to the INP budget, resulting cloud microphysics, and climate forcing than is currently considered
