Climate Futures for Tasmania: output of the 14 km resolution simulation of the Cubic Conformal Atmospheric Model (CCAM) over Tasmania, using the GFDL 2.0 model and the IPCC A2 scenario

Output of downscaling the GFDL 2.0 General Circulation Model (GCM) simulation with the A2 SRES emissions scenario using the Cubic Conformal Atmospheric Model (CCAM). The configuration of CCAM used is 48x48 cells per face, with the high resolution face centered over Tasmania. The model takes the sea surface temperatures output from the GFDL 2.0 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 modelling 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).

本数据集为采用立方共形大气模式（Cubic Conformal Atmospheric Model, CCAM），针对A2 SRES排放情景下的GFDL 2.0全球环流模式（General Circulation Model, GCM）模拟结果进行降尺度处理所得的输出。所用CCAM配置为每个面包含48×48个网格单元，其高分辨率面以塔斯马尼亚为中心。模式以GFDL 2.0 GCM输出的海表温度作为边界条件输入CCAM，并耦合使用了60km分辨率CCAM运行方案中的谱扩散方法。该配置在高分辨率面的近似分辨率为14km。
建模结果被重投影至覆盖东经142°至150°、南纬38°至45°区域的0.1度网格，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的全部变量，包括气温、相对湿度、降雨量、径流量、土壤湿度、云量、辐射、蒸发量与风速。模拟时段为1961年1月1日至2100年12月31日。
