[gradsusr] Problem Extracting data in netcdf format

[Zablone Owiti]

Hi Rashed,
How can I adjust it to stop overwriting the output? See below the .gs file.

Thanks

'reinit'
'sdfopen gcpcr.nc'
'set x 0.5 360.5'
'set y 1 180'
t = 151
'set sdfwrite rain.nc'
*'set gxout fwrite'
while (t<670)
'set t 't
'define jul=r'
'set t 't+1
'define aug=r' 
'set t 't+2
'define sep=r'
'define jas=(jul+aug+sep)/3'
'sdfwrite jas'
t = t+12 
endwhile
'clear sdfwrite'
;

I guess your loop is overwriting the output file and the output variable as after every loop as the name is same after each iteration...
