Abstract

A key goal of the Accelerated Climate Modeling for Energy (ACME) project is to develop a high resolution, fully coupled Earth system model for the climate simulation and prediction. However, the globally uniform high resolution model is computationally intense. The regionally refined model (RRM) is developed as an economic tool for high resolution model development and studies. In this work, we document the performance of the ACME v1 Contiguous United States (CONUS) RRM with emphasis on longstanding climate model biases over the fine portion (i.e., CONUS) of the grids that are shared by the ACME v1 model, such as convection diurnal cycle, and summertime warm biases. We will examine the results from the free-running and nudging simulations and compare them with the uniformly low and high resolution simulations and observations.
