opening multiple nc files

[Chi Nguyen]

Hi Leila,

Here is my example ctl file to be opened by xdfopen.

DSET    Y%f3_%n2.nc
OPTIONS template
TITLE netCDF file
UNDEF 9.e36
XDEF  lon       201 LINEAR  95.00  0.15
YDEF  lat       201 LINEAR   0.00  0.15
ZDEF  lvl      20 LEVELS  1000.00  950.00  900.00  850.00  800.00  750.00  700.00  600.00  500.00  450.00  400.00  350.00  300.00  250.00  225.00  200.00  175.00  150.00  100.00   75.00
TDEF time 25  LINEAR 00z30OCT2005  1HR
VARS   7
sfc_pres=>ps   1  99 x,y,t
geop_ht=>h  20  99 x,y,z,t
air_temp=>t  20  99 x,y,z,t
mix_rto=>qv  20  99 x,y,z,t
zonal_wnd=>u  20  99 x,y,z,t
merid_wnd=>v  20  99 x,y,z,t
omega=>w  20  99 x,y,z,t
ENDVARS

scf_pres is variable name of netcdf
ps       is variable name for grads

Note the rule: Variable name in grads can't have upper case and can't be longer than 15 characters. Please check the online documentation (I've read somewhere in Grads website). The changing of variable names is not compulsory, unless the above rule is violated.

Cheers, Mai
