Climate Futures for Tasmania: bias-adjusted output of the simulation of the Cubic Conformal Atmospheric Model (CCAM) over Tasmania

Output of downscaling various general circulation models (GCMs) simulations using the A2 and B1 SRES emissions scenario using the Cubic Conformal Atmospheric Model (CCAM) over Tasmania, bias adjusted against current climate. Original files are aggregated in three virtual files for each experiment over the periods: 1961-1999, 2000-2049, 2050-2100.
The configuration of CCAM used is a 48x48 cells per face, with the high resolution face centered over Tasmania. The model takes the sea surface temperatures output from the GCM as boundary conditions into CCAM and uses spectral diffusion from the 60km version of CCAM run in conjunction with this model. This configuration provides an approximate resolution of 14km in the high resolution face.
The output is processed on to a 0.1 degree grid covering the region 142 to 150 degrees East and 38 to 45 degrees South, encompassing mainland Tasmania, Flinders and King Island.
Data is output 6 hourly and includes all CCAM variables, among which: air temperature, relative humidity, rainfall, runoff, soil moisture, cloud coverage, radiation, evaporation and wind speed. The modelling output covers the time period 01/01/1961 up to 31/12/2100.
The GCM data used as forcing was downloaded from The Program for Climate Model Diagnosis and Intercomparison (PCMDI).

本数据集为基于A2与B1 SRES排放情景，使用三次共形大气模式（Cubic Conformal Atmospheric Model, CCAM）对塔斯马尼亚地区多套全球环流模式（General Circulation Models, GCM）的模拟结果进行降尺度处理后得到的成果，且已针对当前气候完成偏差校正。原始模拟文件已按各试验分组，针对1961-1999年、2000-2049年、2050-2100年三个时段分别聚合为三个虚拟文件。
本次采用的CCAM配置为每个网格面包含48×48个网格单元，其高分辨率网格面以塔斯马尼亚为几何中心。该模式以GCM输出的海表温度作为边界条件，并采用与本次模拟配套的60km分辨率CCAM版本的谱扩散方案。此配置下高分辨率网格面的近似空间分辨率为14km。
模拟结果已被插值至覆盖142°E至150°E、38°S至45°S区域的0.1°规则网格，该区域包含塔斯马尼亚主岛、弗林德斯岛与金岛。
数据以6小时间隔输出，涵盖CCAM的全部模拟变量，具体包括：气温、相对湿度、降雨量、径流量、土壤湿度、云量、辐射量、蒸发量与风速。该模拟数据集的时间跨度为1961年1月1日至2100年12月31日。
