CSIRO Dawn to 2100 SRESA2 rsds - GCM Surface downwelling shortwave radiation datasets and trends 1850 to 2100 using the SRESA2 Scenario

The CSIRO Dawn-2100 archive contains datasets for atmospheric, land and oceanographic variables for the approximate period 1850 - 2100 (dependent on model). These have been created through the concatenation of 20th century (20C3M) and other scenario (currently SRESA1B or SRESA2) data from a number of the 25 differant global climate models (GCM) from various countries. The SRESA2_rsds dataset contains the Surface downwelling shortwave flux in air variable for various GCM's and runs (multiple runs being averaged to a single file if existing) under the scenario SRESA2 emissions 2001 to 2100. These variables have also been further analysed to give monthly, seasonal and annual trend data, calculated from a monthly timeseries referenced to the area-weighted mean global warming values. 18 GCM models are available with data for variables being in 12 month, annual and 4 seasons(DJF, MAM,JJA,SON) format with 41 files totaling 5.73 GB as Netcdf files. Available for internal use and analysis by CSIRO staff on the HPSC cherax.

CSIRO Dawn-2100 档案库包含1850年至2100年左右（依模型而定）的大气、陆地与海洋变量数据集。该数据集通过整合20世纪（20C3M）及其他情景（当前为SRESA1B或SRESA2）的数据构建而成，数据源自多国的25种不同全球气候模型（Global Climate Model，以下简称GCM）。其中SRESA2_rsds数据集包含SRESA2排放情景下2001年至2100年期间，多种GCM及其模拟试验的地表下行短波辐射通量变量（若存在多组试验结果，则将其平均为单个文件）。上述变量亦经进一步分析，生成了月、季及年度趋势数据，该数据由以面积加权平均全球变暖值为基准的月度时间序列计算得到。当前共提供18种GCM的变量数据，数据格式涵盖月度、年度及4个季节（DJF、MAM、JJA、SON），总计41个网络通用数据格式（Network Common Data Form，简称NetCDF）文件，总容量达5.73 GB。该数据集仅供CSIRO员工在HPSC cherax平台上进行内部使用与分析。
