hi,
目的是修改将扰动加入到一个wrfinput文件中,使用addfile("","w")对原始文件修改,但是出来的结果却多出了很多维数变量。
下面是我的脚本:
+++++++++++++++++++++++++++++++++++++++++++++++
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/wrf/WRF_contributed.ncl"
begin
datadir="./"
file1="wrfinput_d01_c00.c00"
file2="wrfinput_d01_p01.p01"
file3="wrfinput_d01.d01"
file4="wrfinput_d01.d01_new"
ff1=addfile(datadir+file1+".nc","r")
ff2=addfile(datadir+file2+".nc","r")
ff3=addfile(datadir+file3+".nc","w")
varnames1=getfilevarnames(ff1)
varnames2=getfilevarnames(ff2)
varnames3=getfilevarnames(ff3)
varlens=dimsizes(varnames1)
do i=1,varlens-1
print(i+" "+varnames3(i)+" "+varnames1(i)+" "+varnames2(i))
ss=(ff3->$varnames3(i)$) + (ff1->$varnames1(i)$) - (ff2->$varnames2(i)$)
ff3->$varnames3(i)$=ss
delete(ss)
end do
;dimnames=getvardims(ff3)
;delete([/dimnames(12:336)/]) 经过测试,发现这两行不管用
end
+++++++++++++++++++++++++++++++++++++++++++++++

请教,这个怎么将这些多余的维数变量在源文件中给删除掉?
谢谢
