ncl读取wrf_out数据求问

男紫汗

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
begin
fin=addfile("/public/home/****/wrfout_d02_2009-08-06_18.nc","r")
hello=fin->U
fout="d02_08-06_18.dat"
system("/bin/rm -f "+fout)
setfileoption("bin","WriteByteOrder","BigEndian")
fbinrecwrite(fout,-1,hello)   ;(fout,-1,fin->U)
end
像这样读取某个变量并转换成binary格式可行不？
