Absorbing aerosol from biomass burning impacts the hydrological cycle and fluxes of radiation both directly and indirectly via modifications to convective processes and cloud development. Using the ICON model in a regional configuration with convection-permitting resolution of 1500 m, we isolate the response of the Amazonian atmosphere to biomass burning smoke via enhanced cloud droplet number concentrations Nd (aerosol-cloud-interactions; ACI) and changes to radiative fluxes (aerosol-radiation-interactions; ARI). We decompose ARI into contributions from surface cooling (reduced surface shortwave flux) and localized heating of the smoke layer. We show that ARI influences the formation and development of convective cells: surface cooling below the smoke drives suppression of convection that increases with the smoke optical depth, whilst the elevated heating promotes initial suppression and subsequent intensification of convection overnight; a corresponding diurnal response from high precipitation rates is shown. Enhanced Nd (ACI) perturbs the intensive cloud properties and suppresses low-to-moderate precipitation rates. Both ACI and ARI result in enhanced high-altitude ice clouds that have a strong positive longwave radiative effect. Changes to low-cloud coverage (ARI) and albedo (ACI) drive an overall negative shortwave radiative effect, that slowly increases in magnitude due to a moistening of the boundary layer. The overall net radiative effect is dominated by the enhanced high-altitude clouds, and is sensitive to the plume longevity. The considerable diurnal responses that we simulate cannot be observed by polar orbiting satellites widely used in previous work, highlighting the potential of geostationary satellites to observe large-scale impacts of aerosols on clouds.
