Hysplit atmospheric back-trajectories at 10m, 500m, 1000m, 1500m, 2000m, 2500m, 3000m, 3500m, 4000m collected during the SIPEX II voyage of the Aurora Australis, 2012

The current data set contains:Hysplit back-trajectories and IDL readerTrajectories were launched from the SIPEX II ship location every hour at 10m, 500m, 1000m, 1500m, 2000m, 2500m, 3000m, 3500m, 4000m. Three different meteorological reanalyses datasets (ECMWF, GDAS and NCEP were used to generate these 10 day air parcel back-trajectories.本数据集包含HYSPLIT反向轨迹文件与交互式数据语言（IDL）读取工具：轨迹每小时从SIPEX II科考船站位处发射，发射高度涵盖10米、500米、1000米、1500米、2000米、2500米、3000米、3500米及4000米；本次轨迹生成采用欧洲中期天气预报中心（ECMWF）、全球数据同化系统（GDAS）与美国国家环境预报中心（NCEP）三种气象再分析数据集，生成了时长为10天的气团反向轨迹。
