overlay功能例子中
http://www.ncl.ucar.edu/Applications/Scripts/overlay_12.ncl

数据在官网下了,是wrfout_d01_2003-07-15_00_00_00.txt,用ncdump可以打开开内容,也改名了.nc和无后缀都不行。。。
想不通。。。

代码第25行起部分如下:
begin
;---Open file. You may need to include ".nc" at the end.
a = addfile("wrfout_d01_2003-07-15_00:00:00.nc","r")

;---Read variables directly (can also use "wrf_user_getvar")
hgt = a->HGT(0,:,:)                 ; terrain, 0 is the first time step
lat = a->XLAT(0,:,:)                ; latitude
lon = a->XLONG(0,:,:)               ; longitude
znu = a->ZNU                        ; eta values
dbz = wrf_user_getvar(a,"dbz",0)    ; reflectivity

nlev = 1
print("Plotting at level " + znu(0,nlev))

读数据文件这个问题搞定了,是win系统的问题,我直接用linux系统下的数据文件就ok,用win系统下载的就不能读。。。之前别的同事也遇到过,个别数据会这样,

报错,关于“wrf_user_getvar”,查了下,把这两行放出来了
  load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
  load "$NCARG_ROOT/lib/ncarg/nclscripts/wrf/WRFUserARW.ncl"

然后报错。。。一大片。。。
