; 2、利用可视化软件panoply或者linux端安装cdo或者nc_filedump(only for .NC)。 ; 3、利用ncl-printVarsummary ;;; 第一步读取数据,下面主要以nc数据为例橙色字体为NCL自带函数,可在官网搜索 f =addfile("precip.nc","r") precip = f->precip ;傻瓜式读取 ; 与之相反的是有意识地读取。那么问题来了什...
1、ncl_filedump命令(未进入ncl):ncl_filedump文档 打开终端,输入ncl_filedump hgt.mon.mean.nc,注意数据文件的路径!!要么先cd到当前目录下(如下图),要么在.nc文件名前加入相对路径! Fig.3.png 2、ncl导入数据后再查看: 打开终端,输入ncl按回车进入ncl命令行模式中。输入: f = addfile(".../hgt.mon....
可用NCL的内置函数getfilevaratts从名为"file.nc”文件中读取变量“slp"所有属性 fid = addfile("file.nc","r") file_atts = getfilevaratts(fid,"slp") 1. 2. 或通过isatt确认某个变量是否存在某个属性: if(isatt(slp,"units")) then print(slp@units) end if 1. 2. 3. 字符串引用 应用情况...
