[已解决]ncl 转换GFS数据为nc格式之后的变量说明

莎朗嘿哟YY

想请教下各位大神，我现在用ncl中的ncl_convert2nc将gfsanl_4_20170502_0000_000.grb2这种GFS数据转换成nc格式，转换好了之后，我ncdump转换出来的nc数据，如下：我想知道这些变量是什么含义？我现在需要2米温度，10米U,V，这里面的变量哪个代表这三个变量呢？有没有说明文件，谢谢~

您好。。。请问您解决了吗？
这里面有好多的风速。实在不知道应该用哪一个。。。

你ncdump看一下变量的说明，再看下变量括号里的变量是第几层就知道啦

比如这个变量float TMP_P0_L103_GLL0(lv_HTGL2, lat_0, lon_0) ;你看下lv_HTGL2包含了哪几层就知道了，ncdump看一下

您好，我最近也在学这个的数据变量，有个等位涡面  Potential vorticity Level，它的层高信息是编号：500、1000、1500、2000、34768、34268、33268、33768，这个您知道分别代表PV等于多少的层吗？如果知道，求回复

学习了，用这个命令看好了

学习了，变量真的太多了，完全不知道什么意思
