HAPpy Hour- Resolution Simulations of Marine Cloud Brightening in Decoupled Marine Boundary Layers

Abstract- In Marine cloud brightening (MCB), aerosol particles are sprayed in cloud-topped boundary layers to increase cloud albedo and reflect more shortwave solar radiation back to space to counteract global warming. While the typical focus of MCB lies on stratocumulus clouds due to their large global cloud cover and typical high susceptibility to spraying, we focus on local applications of MCB under trade wind cumulus conditions, such as in the Great Barrier Reef, where MCB is envisioned to mitigate marine heat waves that could lead to coral bleaching events. Three-dimensional LES simulations with detailed Lagrangian cloud microphysics were performed. Emphasis was placed on the dispersion of the sprayed plume, the vertical transport of the sprayed aerosol, its mixing with clouds and the accurate representation of small-scale mixing.
