CSIRO - SEACI 2006 - South East Australian Climate Initiative regional climate model data 1950-2000

The CSIRO arcive of the South East Australian Climate Initiative (SEACI) Regional Climate Model dataset for the Murray Darling Basin region for the years 1950-2000. Created with the CSIRO Cubic Conformal Atmospheric Model (CCAM) Regional Climate Model (RCM) by dynamically downscaling the NCEP reanalysis model output over a target area centered on south eastern Australia. SEACI is a research program investigating the causes and impacts of climate change and climate variability across this region. The CCAM model was nested in the NCEP host with 50 years of NCEP output being used, with greenhouse emissions corresponding to 1950-2000. 4X-Daily, monthly and seasonal atmospheric variables are available between Lat: -5, -50 & Lon: 130, 160 at 5 levels (1000, 850, 700, 500, 300 hPa) with .2º (20km) resolution. There are 678 daily files totalling 1.81 TB, and 1093 monthly_mean & seasonal files totaling 46.8 GB. All files are in netcdf format and are available for internal use and analysis by CSIRO staff on the HPSC cherax.澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）存档的东南澳大利亚气候倡议（South East Australian Climate Initiative, SEACI）针对墨累-达令盆地的区域气候模型数据集，时间跨度为1950年至2000年。该数据集通过对以澳大利亚东南部为中心的目标区域内的美国国家环境预报中心（National Centers for Environmental Prediction, NCEP）再分析模型输出结果进行动力降尺度，使用CSIRO三次共形大气模型（Cubic Conformal Atmospheric Model, CCAM）区域气候模型（Regional Climate Model, RCM）生成。SEACI是一项旨在研究该区域气候变化与气候变率的成因及影响的科研项目。CCAM模型嵌套于NCEP宿主模型中，实验采用了50年的NCEP再分析输出数据，温室气体排放情景匹配1950-2000年时段。数据集包含每日4次、逐月及逐季的大气变量，空间覆盖纬度范围-5°至-50°、经度范围130°至160°，涵盖5个气压层（1000、850、700、500、300 hPa），空间分辨率为0.2°（约20公里）。数据集包含678个每日数据文件，总容量达1.81 TB；另有1093个逐月平均及逐季数据文件，总容量为46.8 GB。所有文件均采用网络通用数据格式（netCDF）存储，可供CSIRO员工在HPSC Cherax高性能计算集群上进行内部使用与分析。
