[ncl-talk] Time, lat and lon information is missing in created file

[Mary Haley]

Amit,

Your code looks correct, so it may be the input data that's the issue.

You should always do a "printVarSummary" on any variables that aren't
producing the expected metadata.

What does the following report:

printVarSummary(tasmax)
printVarSummary(b)

You can try this script as an example:

 infile  = "$NCARG_ROOT/lib/ncarg/data/cdf/uv300.nc"
 outfile = "test.nc"
 f = addfile(infile,"r")
 u = f->U(:,{25:50},{-100:100})
 b = u
 printVarSummary(u)

;---Write to new file
 system(" rm -rf " + outfile)
 ncdf = addfile(outfile,"c")
 filedimdef(ncdf,"time",-1,True)
 ncdf->u = u

;---Close the file
 delete(ncdf)

;---Open new file and read coordinate arrays
  a = addfile (outfile,"r")
  time = a->time
  lat  = a->lat
  lon  = a->lon
  print(time)
  printVarSummary(lat)
  printVarSummary(lon)
  printMinMax(lat,0)
  printMinMax(lon,0)
