官网的具体步骤
- Add Jiuquan station into the project..
- Calculate 3-day back trajectories during PM10 data measurement period.
- Convert end point files to .tgs files. Then join .tgs files to one file.
- Convert .tgs file to trajectory line shape file and add the shape file into the project.
- Show press profile of the trajectories.
- Add measurement data into the trajectories.
- Select polluted trajectories.
- Cluster calculation to the trajectories.
- Calculate mean trajectory of cluster and add the cluster line shape file into the project.
- Decide cluster number.
- Add cluster to each trajectory.
- Do cluster statistics and find the pathways of SDS.
- Create grid polygon shape layers of PSCF and CWT.
- PSCF and CWT analysis.
目前已将hysplit 输出格式转为tgs文件,进而可以实现后续的操作,基本没有问题
王老师 @MeteoInfo 顺便问一下,这个默认标记筛选的轨迹的黄色可以自定义么?
另外hysplit可以额外输出很多变量 比如PRESSURE,AIR_TEMP,RAINFALL,MIXDEPTH,RELHUMID,SPCHUMID,H2OMIXRA,TERR_MSL
但是转成shp文件的时候并没有添加进去我下载的java版本的好像看不到源代码,不知道有什么方法添加进去呢?
