Climate Futures for Tasmania: output of the 60 km resolution simulation of the Cubic Conformal Atmospheric Model (CCAM) over Tasmania, using NCEP2 sea surface temperature and atmospheric forcing

Output of downscaling NCEP reanalysis 2 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. This model was forced from raw NCEP data using both sea surface temperature and atmospheric forcing. 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 to 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 30/11/2006.
This model simulation was designed to allow downscaling to a high resolution (0.1 degree) version of CCAM centered over Tasmania.

本数据集为使用三次共形大气模式（Cubic Conformal Atmospheric Model，CCAM）对NCEP再分析资料2（NCEP reanalysis 2）进行降尺度得到的输出结果。本次所用CCAM的配置为每个面包含64×64个网格单元，其高分辨率面以澳大利亚为中心。该模式以原始NCEP数据为基础，结合海表温度（sea surface temperature）与大气强迫场（atmospheric forcing）进行驱动。此配置下，高分辨率面的近似分辨率为60公里。
输出数据经后处理后匹配至覆盖125°E至170°E、25°S至50°S区域的0.5度经纬网格，该区域涵盖澳大利亚东南部全境（覆盖南澳大利亚州）、塔斯马尼亚州以及新西兰西南端。
数据以6小时间隔输出，包含CCAM的全部变量，其中包括：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。该模拟结果的时间跨度为1961年1月1日至2006年11月30日。
本次模式模拟的设计目标是支持以塔斯马尼亚为中心的0.1度高分辨率CCAM版本的降尺度工作。
