Climate Futures for Tasmania: output of the 60 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 being used is a 64x64 cells per face, with the high resolution face centered over Australia. The model takes the sea surface temperatures output from the GFDL 2.0 GCM as boundary conditions into CCAM. This configuration provides an approximate resolution of 60km in the high resolution face.
The output is processed on to a 0.5 degree grid covering the region 125 - 170 degrees East and 25 to 50 degrees South, encompassing all of south-east Australia (extending over South Australia, Tasmania and the south-west tip of New Zealand).
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.
This model simulation was designed to allow downscaling to a high resolution (0.1 degree) version of CCAM centered over Tasmania.
The GCM data used as forcing was downloaded from The Program for Climate Model Diagnosis and Intercomparison (PCMDI).

本数据集为采用三次共形大气模式（Cubic Conformal Atmospheric Model, CCAM），针对A2 SRES排放情景下GFDL 2.0通用环流模式（General Circulation Model, GCM）的模拟结果进行降尺度处理后的输出产物。本次使用的CCAM配置为每个面包含64×64个网格单元，其中高分辨率面以澳大利亚为几何中心。该模式将GFDL 2.0 GCM输出的海表温度作为边界条件输入CCAM，此配置在高分辨率面的近似空间分辨率为60公里。
处理后的输出数据被重采样至覆盖东经125°至170°、南纬25°至50°的0.5度网格，该区域囊括整个澳大利亚东南部，包括南澳大利亚州、塔斯马尼亚州以及新西兰的西南端区域。
数据以6小时间隔进行输出，包含CCAM的全部模拟变量，具体包括：气温、相对湿度、降水量、径流量、土壤湿度、云量、辐射、蒸发量与风速。该模拟的时间跨度为1961年1月1日至2100年12月31日。
本模型模拟的设计初衷是支持以塔斯马尼亚为中心的0.1度高分辨率CCAM版本的降尺度研究。
