Soot Aerodynamic Size Selection for Optical Properties

Atmospheric particles that absorb sunlight have an important influence on the Earth’s climate but quantifying this has been difficult because climate models use uncertain, simplified treatments of aerosol optical properties that demonstrate little consistency between top-down and bottom-up assessments. SASSO will address this longstanding knowledge gap by uniquely combining several recent advances in instrumentation and experimental techniques for the first time to provide authoritative, detailed optical data on black and brown carbon. We will then use this data to challenge detailed radiative transfer models (incorporating mixing states) in order to develop improved descriptions of black and brown carbon radiation interactions in the UK’s state-of-the-art
climate model to provide more accurate assessments of future climate scenarios.
