CSIRO Dawn to 2100 SRESA1B vas - GCM Northward wind near surface datasets 1850 to 2100 using the SRESA1B 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 SRESA1B_vas dataset contains the Northward wind near surface variable for various GCM's and runs (multiple runs being averaged to a single file if existing) under the SRESA1B scenario (SRESA1B emissions 2001 to 2100, then constant GHG 720ppm). 19 GCM models are available with data for variables being in 12 month, annual and 4 seasons(DJF, MAM,JJA,SON) format with 36 files totaling 3.66 GB as Netcdf files. Available for internal use and analysis by CSIRO staff on the HPSC cherax.

CSIRO Dawn-2100档案库包含覆盖约1850年至2100年（依具体气候模型而定）的大气、陆地及海洋学变量数据集。该数据集通过拼接20世纪气候耦合模式比较计划（20C3M）与其他情景（当前为SRESA1B或SRESA2）的数据构建而成，所用数据源自多个国家的25种全球气候模式（GCM）。SRESA1B_vas数据集包含SRESA1B情景下各全球气候模式的近地面北向风变量及对应模拟运行结果——若存在多组运行结果，则将其平均为单个文件；SRESA1B情景指2001年至2100年实施SRESA1B排放方案，此后温室气体（GHG）浓度恒定为720ppm。目前共有19款全球气候模型可提供相关数据，变量数据涵盖12个月尺度、年际尺度及四个季节（DJF冬季、MAM春季、JJA夏季、SON秋季）三种格式，以NetCDF格式文件存储，总计36个文件，总容量3.66 GB。该数据集仅限CSIRO员工在HPSC Cherax高性能计算集群上开展内部使用与分析工作。
