Utilizing HiRAM for long-term high-resolution climate experiments is one of the major activities in ACCC. Three periods of time-slice experiments following CMIP5 RCP scenarios have been conducted with HiRAM for the present time (1979-2015), near future (2040-2065), and end of the century (207-2100). These HiRAM simulations and projections also have been provided to Taiwan’s research community for dynamical downscaling to understand future climate change and its impact on Taiwan. Other than HiRAM simulations and projections under CMIP5 RCP scenarios, I further utilized HiRAM and HiRAM-SIT to participate in CMIP6-HighResMIP. There are three tiers of HR (high resolution) and LR (low resolution) simulations in the CMIP6-HighResMIP protocol. In ACCC, HiRAM was used for the atmosphere-only uncoupled simulations in Tier1 (1950-2014) and Tier3 (2015-2100), while HiRAM-SIT was used for the atmosphere-ocean coupled simulations in Tier2 (1950-2100). For high- and low-resolution simulations, C384 (~25km) was used as HR experiments, and C192 (50km) was used as LR experiments. The high-resolution 0.25o daily SST (sea surface temperature) datasets, Hadi2SST, were used as prescribed SST in the atmosphere-only experiments and nudged SST in the coupled HiRAM-SIT simulations. The other high-resolution 0.25o daily SIC (sea ice concentration) dataset, Hadi2SIC, was used as the prescribed sea ice concentration in both HiRAM and HiRAM-SIT simulations. Additional three tiers of HR and LR simulations driven by 1o SST and 1o SIC from the coupled model TaiESM1 were also conducted from 1950-2100. There is a total of 800 years of CMIP6-HighResMIP data produced from HiRAM/HiRAM-SIT with C384 and C192 resolutions, respectively. They are driven by HadISST2 0.25o daily SST and SIC datasets and 1o monthly TaiESM1 SST and SIC. The model descriptions, experiment introductions, and the preliminary analysis of CMIP6-HighResMIP simulations using HiRAM/HiRAM-SIT are described in the RCEC 2022 technical report. A more comprehensive analysis is available on this website: http://220.127.116.11/~cpc9682/HiRAM_analysis/.
The total output for CMIP6-HighResMIP HiRAM/HiRAM-SIT experiments is 939 TB. Due to the vast amount of data, only daily and monthly outputs with a size of about 22 TB were uploaded to the RCEC's Earth System Grid Federation (ESGF) node. The experiments and outputs index information are uploaded to DKRZ's ESGF-CoG node. The DOI of HiRAM/HiRAM-SIT data is available from ESGF: https://www.wdc-climate.de/ui/cmip6?input=CMIP6.HighResMIP.AS-RCEC.HiRAM-SIT-HR.
