Re: Reading variable only

It is not clear to me what you want to do. Further, the code
snippet is not legal: eg: vNames = dimsizes(vNames)

    fils = (/"station_data_1.nc","station_data_2.nc",..../)
    nfils = dimsizes(fils)

    f = addfile (fils(0),"r") ; read from 1st file
    vNames = getfilevarnames(f)
    print(vNames)

    nv = ? ; use vNames to select the index

    do nf=0,nfils-1
       f = addfile (fils(nf),"r")
       V = f->$vNames(nv-1)$
       printVarSummary(V)
     end do

===
The print(vNames) might look like

Variable: vNames
Type: string
Total Size: 48 bytes
             5 values
Number of Dimensions: 1
Dimensions and sizes: [6]
Coordinates:
(0) lat
(1) lon
(2) gw
(3) time
(4) U

Then nv = 4
