[ncl-talk] FW: Problem in writing the output from netcdf file

[Muhammad Omer Mughal]

Hi everyone

I am running NCL version 6.1.0. I have to write output from multiple netcdf file into the ascii fromat containing wind speed comparison at a particular latitude and longitude.This aim is to get the comparison from the wrf ouput and the instrument at a particular location. The netcdf files are from the instrument but are not in the regular netcdf format meaning that the time is not included in the dimensions of the variables  to be extracted  and each file contains one value of time.?The first problem that I am facing is that the fill value is not getting deleted in the ascii output.I use the following to generated the ascii output .

b=addfile("/20090711/20090711_000239_01_g.nc","r")
lon=b->yp(0,0,:)
lat=b->xp(0,:,0)
DATADir = "./"
fils = systemfunc (" ls -1 " + DATADir + "/20090711* ")
numfils = dimsizes(fils)
do j = 0,numfils-1,1
a = addfiles(fils(j)+".nc","r")
time=a[:]->time
::::::::::::::
::::::::::?
       npt  = npt + 1
       data(npt) = sprinti("%0.5i", (npt+1) )
       data(npt) = data(npt) + sprintf("%7.1f ",lat(nl))
       data(npt) = data(npt) + sprintf("%7.1f ",lon(ml))
      do nt=0,ntim-1
         data(npt) = data(npt) + sprintf("%10.3f ", x(nt))
data(npt) = data(npt) + sprintf("%7.1f ",u1(nt,nl,ml))
data(npt) = data(npt) + sprintf("%7.1f ",v1(nt,nl,ml))
      end do
    end do
  end do
  asciiwrite (fName , data)
?In this way I get the output that is attached .Any help to correct this code will be appreciated
