This 26-minute lecture by Beiping Luo explores the complex dynamics of "Stratospheric aerosol injection across scales (SAIaS)" - from near-field agglomerates and size distributions to their global and regional impacts. Learn about a research project investigating how sub-grid processes in earth system models (ESMs) affect particle size distribution and morphology over various time and space scales, particularly in the 1 millisecond to 1 hour range. Discover how this research generates physics-based input parameters for ESMs to quantify the radiative impact of stratospheric aerosol injection, tracking particles from their emission into the stratosphere to re-entry into the troposphere. This presentation is part of the Simons Foundation's Solar Radiation Management Annual Meeting 2025.
