This work documents the first version of U.S. Department Energy (DOE) new Exascale Earth System Model (E3SMv1). We focus on standard resolution fully coupled physical model designed to address DOE mission-relevant water cycle questions. Its components include atmosphere and land (110-km grid spacing), ocean sea ice (60 km in midlatitudes 30 at equator poles), river transport (55 km) models. base configuration will also serve as a foundation for additional configurations exploring higher...
Researchers increasingly use meta-analysis to synthesize the results of several studies in order estimate a common effect. When outcome variable is continuous, standard meta-analytic approaches assume that primary report sample mean and deviation outcome. However, when skewed, authors sometimes summarize data by reporting median one or both (i) minimum maximum values (ii) first third quartiles, but do not deviation. To include these meta-analysis, methods have been developed from reported...
Abstract The Energy Exascale Earth System Model Atmosphere version 1, the atmospheric component of Department Energy's is described. model began as a fork well‐known Community Model, but it has evolved in new ways, and coding, performance, resolution, physical processes (primarily cloud aerosols formulations), testing development procedures now differ significantly. Vertical resolution was increased (from 30 to 72 layers), top extended 60 km (~0.1 hPa). A simple ozone photochemistry predicts...

Abstract. Climate simulations with more accurate process-level representation at finer resolutions (<100 km) are a pressing need in order to provide detailed actionable information policy makers regarding extreme events changing climate. Computational limitation is major obstacle for building and running high-resolution (HR, here 0.25∘ average grid spacing the Equator) models (HRMs). A affordable path HRMs use global regionally refined model (RRM), which only simulates portion of globe HR...
