CAS FGOALS-f3-H and CAS FGOALS-f3-L outputs for the high-resolution model intercomparison project simulation of CMIP6

Abstract

The High Resolution Model Intercomparison Project (HighResMIP) is a unique model intercomparison project in phase 6 of the Coupled Model Intercomparison Project (CMIP6), which is focused on the impact of horizontal resolutions. The outputs of the high- and low-resolution versions of CAS FGOALS-f3-H and CAS FGOALS-f3-L for the experiments of the HighResMIP simulations in CMIP6 are described in this paper. The models and their configurations, experimental settings, and post-processing methods are all introduced. CAS FGOALS-f3-H, with a 0.25° horizontal resolution, and CAS FGOALS-f3-L, with a 1° horizontal resolution, were forced by the standard external conditions, and two coordinated sets of simulations were conducted for 1950–2014 and 2015–50 with the Experiment IDs of ‘highresSST-present’ and ‘highresSST-future’, respectively. The model outputs contain multiple time scales including the required hourly mean, three-hourly mean, six-hourly transient, daily mean, and monthly mean datasets. It is reported that the 0.25° CAS FGOALS-f3-H successfully simulates some of the key challenges in climate modeling, including the average lifetime of tropical cyclones, particularly in the western parts of the northern Pacific Ocean, and the diurnal cycle of hourly precipitation. These datasets will contribute to the benchmarking of current models for CMIP, and studies of the impacts of horizontal resolutions on climate modeling issues.
