[gradsusr] Displaying a .nc file

[Hosmay Lopez]

David,

You should let GrADS know that the file is a netCDF. You do that by adding the following text line in your control file:

DTYPE netcdf

Insert such after the UNDEF line.

Good luck!

So I figured out how to use a descriptor file but I am still having troubles opening the file. My descriptor file is as follows:

DSET   ^atmos_month.nc.0000
UNDEF  1.e-10
TITLE 6 Months Sample Model Output
*
XDEF 96 LINEAR  0.0   3.75
*
YDEF 80 GAUSR30 1
*
ZDEF 18 LEVELS  1000 950 900 850 800 750 700 650 600 550 500 450 400 350 300
250 200 150
*
TDEF 804  LINEAR JAN0 1MO
*
VARS 7
u   18   0  u
v   18   0  v
w   18   0  v
t   18   0  v
sh   18   0  v
rh   18   0  v
z   18   0  v
ENDVARS

It was able to open it without issue:


ga-> open cont.ctl

Scanning description file:  cont.ctl

Data file atmos_month.nc.0000 is open as file 1

LON set to 0 360

LAT set to -88.29 88.29

LEV set to 1000 1000

Time values set: 0:1:1:0 0:1:1:0

E set to 1 1


However, I am having trouble displaying the data. I tried to use the display command (d) with this result:


ga-> d atmos_month.nc.0000

Syntax error: Bad file number for variable atmos_month

  Error ocurred at column 1

DISPLAY error:  Invalid expression

  Expression = atmos_month.nc.0000


Is my syntax off?


Thanks,


David
