[ncl-talk] error in dimension

[Ehsan Taghizadeh]

Dear KarinI think so, all files have the same dimensions and names.I examined one by one files and all shows same output for following lines  prc2 = f->precipitationCal(lat | :, lon | :)
  printVarSummary(prc2)

Output is:

Type: float
Total Size: 28304 bytes
            7076 values
Number of Dimensions: 2
Dimensions and sizes:   [lat | 61] x [lon | 116]
Coordinates:
            lat: [34.25..40.25]
            lon: [40.05..51.55]


 
However if it helps I could attach these files.

  Hi Ehsan,
 
 the syntax for multiple files is correct
 
   prc = f[:]->precipitationCal(lat|:,lon|:)
 
 Are you sure that all files have the same dimensions and names?

  Dear Karin Thank you so much for your nice reply. However for   prc    = f[:]->precipitationCal
    printVarSummary(prc)

  Variable: prc Type: float Total Size: 849120 bytes             212280 values Number of Dimensions: 2 Dimensions and sizes:   [lon | 3480] x [lat | 61] Coordinates:             lon: [40.05..51.55]             lat: [34.25..40.25] Number Of Attributes: 6   units :       mm   long_name :   Daily accumulated precipitation (combined microwave-IR) estimate   coordinates : lat lon   _FillValue :  -9999.9   origname :    precipitationCal   fullnamepath :        /precipitationCal 
  In fact for one file, I don't have any problem and following lines work correctly:
     f = addfile(filess,"r")   prc = f->precipitationCal(lat | :, lon | :)
  
  however for multiple files I counter problem. I attached 3 files which I want to open. As Karin mentioned the problem is related to "Dimenstions and sizes". So how could I point to a variable and simultaneous reorder (lat, lon) dimension in case of multiple files? I mean what is the form of    f = addfile(filess,"r")   prc = f->precipitationCal(lat | :, lon | :) for multiple files? 
  Again I'll be thankful for any help. 
  Sincerely Ehsan

     Hi Ehsan,
 
 please, have a look at your data first. Do
 
   prc    = f[:]->precipitationCal
   printVarSummary(prc)
 
 to see what dimension names precipitationCal has.

   Hi, I want to open multiple netcdf files. Also I had to change dimesion of variable (precipitationCal(lat | :, lon | :)), but I got an error (fatal:(lat) is not a dimension name in variable (lon), could not determine  dimension number). What should I do? Following lines are simple code. 
     diri = "path/"   ; input directory    files = systemfunc("ls "+diri+"3B-DAY-L.MS.MRG.3IMERG.201704*.nc") ; file paths    f = addfiles(files,"r")   prc    = f[:]->precipitationCal(lat | :, lon | :)        ; read precipitation from all files
