title: Dataset 3 of RegCM5 ensemble climate change projections over mid-high latitudes Northern Asia
title: 亚洲中高纬度地区RegCM5区域气候模式气候变化集合预估数据集3

description: The dataset is based on the ensemble of climate change experiments conducted by RegCM5 over mid-high latitudes Northern Asia region. In the experiments, the RegCM5 domain encompasses Northeast and Northwest China, Mongolia, Kazakhstan, Eastern Europe Plain and Siberia in Russia, northern part of Japan, and the adjacent areas and oceans. The model is run at 25 km gird spacing, with its standard configuration of 18 vertical sigma layers and model top at 10 hPa. It is driven by three CMIP6 models of EC-Earth3-Veg, MPI-ESM1-2-HR, and NorESM2-MM. The model simulations include two time slices, 1995 to 2014 for the present day climate, and 2080 to 2099 for the future under the emission pathway of SSP2-4.5. For the model configuration, CLM4.5 land surface process model, planetary boundary layer scheme of UW, Tiedtke cumulus convection scheme, resolved scale micro-physics process described by WSM5 from the WRF modeling system, Xu-Randall empirical scheme to represent cloud fraction, and radiation package from the NCAR Community Climate Model CCM3 for atmospheric radiation transfer, are selected. RegCM5 output is post processed into standard CORDEX format. The time scale is 3hr (for selected variables), 6hr (for selected variables), daily mean, and horizontal resolution as 25 km × 25 km, with grid numbers of 307 (east-west)×220 (north-south).The variables included in this dataset：rlds(Surface downwelling longwave radiation), rlus(Surface upwelling longwave radiation), rlut(TOA outgoing longwave radiation), rsds(Surface downwelling shortwave radiation), rsdt(TOA incident shortwave radiation), rsus(Surface upwelling shortwave radiation), rsut(TOA outgoing shortwave radiation), sfcWind(Near-surface wind speed), sfcWindmax(Daily maximum near-surface wind speed), uas(Eastward near-surface wind), ua100m(Eastward wind at 100m), ua200(Eastward wind at 200hPa, similar to later), ua250, ua300, ua400, ua500, ua600, ua700, ua850, ua925, ua1000.Format of file names:&lt;variable&gt;_NA_&lt;driving_source_id&gt;_&lt;driving_experiment_id&gt;_r1i1p1f1_ICTP_RegCM5-0_v1-r1_&lt;frequency&gt;_&lt;StartTime&gt;-&lt;EndTime&gt;.ncDirectory structure:/CMIP6/DD/NA/ICTP/&lt;driving_source_id&gt;/&lt;driving_experiment_id&gt;/r1i1p1f1/RegCM5-0/v1-r1/&lt;frequency&gt;/&lt;variable&gt;
