试过用era5,也是报错同样问题
我不确定自己理解的对不对
这一部分的代码,是不是就是根据bbox的范围,去获取这个bbox矩形下的所有gpm/gfs/era5数据,那是不是如果我们已经下好了数据,只需要根据bbox的值,去把这个数据切割一下,效果是一样的
里面目前我唯一不太理解的参数是time_chunks是用来做什么的
额,这部分文档是老的,读数据还是参照opendata的文档,time_chunks是dask分块,可以并行提高读取速度?
有问题的代码贴出来看一下
报错的代码就是上面贴图的那部分代码,跑到[In]13时会报错,还是想知道我理解的那部分有没有问题,如果没问题的话,和后面的工作没有影响

在docs/examples/mean/mask.ipynb下
使用wis_s3api,或者opendata下的s3api,都会报错:
