有点长 .....还希望能稍微耐心看哈,大家随便扫一眼,最下面的grib的CDL文件
也算是熟悉一下 grib数据里面的描述内容啦 哈哈哈 谢谢 \(^o^)/~
最近 从 ncarg 上面 下载数据
http://rda.ucar.edu/datasets/ds335.0/index.html#cgi-bin/datasets/getSubset?dsnum=335.0&listAction=customize&gindex=9&_da=y
数据选择如下
用 ncl 查看了里面的数据内容 cdl 大概描述如下: 我想用海表10m 风场 数据》?看了半天也不知道那个是?
打算自己插值
可如果要自己插值的话 用哪个数据比较贴近,海表边界层 呢?????? 求大家给出个主意撒
