[ncl-talk] Fw: read and plot multiple files with different sizes

[Ehsan Taghizadeh]

 Dear DennisI really appreciate for your comments. You are right and after doing your suggestion (use the := syntax), script works correctly.

---------------------
By default, NCL is a strongly typed language. It will not allow certain operations.

 You can use the NCL reassignment operator    :=

Consider:

float  a(10)
double b(10)
float c(30)

By default:
    a  = b     ; NCL will issue a FATAL error; it will not allow a double=> float because information may be lost
    a := b     ; NCL will truncate

    a  = c     ; FATAL ... it will not allow an array of size 30 to be reassigned to an array that is size 10
    a := c     ; NCL will overwrite

So I suggest going over your script and anyplace you this a size and or type might change ... use the := syntax.I

Hi,First I want to say thank you for your help about my previous problem. I think this committee is really fast in helping and answering.However I have another problem and I'll be thankful if I could have your help again.I want to draw SMAP (Soil Moisture Active Passive) data and I use a provided script at following link:https://www.ncl.ucar.edu/ Applications/Scripts/smap_l3_ 2.ncl
which the parent directory is:NCL Applications: HDF, HDF-EOS

Use of NCL to visualize datasets in HDF format.

This script helps to draw multiple files, but after one file I got following error:      fatal:Dimension sizes on right hand side of assignment do not match dimension sizes of left hand side      fatal:["Execute.c":8640]: Execute: Error occurred at or near line 80 in file smap_l3_2.ncl
which mentioned different sizes of my files. For example for one file I have:      float latitude(281024);
and for another file I have:
      float latitude(281711);
and the error arises when the script wants to do following command:     lat2d     = f[nf]->$lat_path$also for     lon2d     = f[nf]->$lat_path$
Attachment is the script and following lines are output of printVarSummary(var):

So how could I read and plot multiple files with different sizes?
