Aerosol particles are of major concern due to their strong impact on climate and health, and soot particles are of special concern.

Soot is to a large extent formed by human activities in incomplete combustion of carbonaceous fuels and commonly contains both highly absorbing graphitic-like black carbon (BC) and organic carbon, often in shades of brown. However, the physiochemical properties of soot vary between sources and changes during aging in the atmosphere. Additionally, the on-going transition to renewable fuels result in soot with other properties, and thus impact on health and climate. This complicates our effort to precisely determine what BC is, how to measure it, and what to do about it. It brings about challenges to our efforts to understand and regulate soot.

Welcome to a workshop on soot!
