The nature and origin of organic aerosol in the atmosphere remain unclear. The gas–particle partitioning of semi-volatile organic compounds (SVOCs) that constitute primary organic aerosols (POAs) and the multigenerational chemical aging of SVOCs are particularly poorly understood. The volatility basis set (VBS) approach. implemented in air quality models such as WRF-Chem (Weather Rese... https://atlanticknifers.shop/product-category/knife-accessories/
