[gradsusr] Problem in loading variables in different files.

[Hang]

Jim,
 
I have just tried to specify the z-level as you mentioned,but the error still 
exist.
 
'sdfopen /home2/h08hang/redata/pres.mon.mean.nc'
'set lat -90 90'
'set lon 0 360'
'set t 1 753'
'set z 1'
'define spres=pres'
'close 1'
 
'sdfopen /home2/h08hang/redata/uwnd10m.mon.mean.nc'
'set lat -90 90'
'set lon 0 360'
'set t 1 753'
'set z 1'
'define uwnd10m=uwnd'
'close 1'
 
'sdfopen /home2/h08hang/redata/vwnd10m.mon.mean.nc'
'set lat -90 90'
'set lon 0 360'
'set t 1 753'
'set z 1'
'define vwnd10m=vwnd'
'close 1'
 
the error message is:
Data Request Error: Invalid grid coordinates
  World coordinates convert to non-integer  grid coordinates
    Variable = vwnd10m  Dimension = 1 
Operation Error:  Error from ave function
  Error ocurred at column 32
DEFINE error:  Invalid expression. 
I guess the problem comes up when I open the next three files (which have 
different grids). I tried several ways and I find out that the defined variables 
seem to follow the file1 that is still opened in the programme. 

For example, if I close the file after the line 'define shum2m=shum' then I 
cannot work with the variables I have defined before (uwnd10m,vwnd10m). but if I 
do not close the file after the line 'define shum2m=shum', then I cannot work 
with the spres i defined before and the "uwnd,vwnd and pres" which will be 
opened afterwards.
 
So any sugesstions to slove this? I am trying to regrid the files as suggested 
by Doug but I am still trying to do on it.
 
Thanks 
 
Henry

Henry:

I think you will need to specify the z-level explicitly in each block 
(right now you just specify x,y,t), e.g.,
...
'set t 1 753'
'set z 1'
...
for each variable.
