The emergence of nonhydrostatic Global Storm-Resolving Models (GSRMs) with kilometer-scale horizontal resolutions marks a pivotal advancement in weather and climate modeling. The U.S. Department of Energy’s Simple Cloud-Resolving E3SM Atmosphere Model (SCREAM) represents a significant step forward, featuring a global atmosphere model with 3 km horizontal grid spacing. This study leverages data from the DOE Atmospheric Radiation Measurement (ARM) Tracking Aerosol Convection Interactions Experiment (TRACER) field campaign to evaluate deep convection simulated by both the regionally-refined and doubly-periodic configurations of SCREAM across a series of case studies. The evaluation encompasses a comprehensive analysis of meteorological conditions, cloud and precipitation characteristics, convective cluster distributions, and convective cell tracking. Additionally, the potential influence of aerosols on simulated deep convection is investigated through a companion simulation that perturbs cloud droplet number concentrations.
