In your script please include the following and use xdfopen to open the<br>

Subject: [gradsusr] opening CAM netcdf files with grads<br>
<br>
hi all,<br>
<br>
I am fairly new to GraDs. I am trying to use GraDs to open a netcdf file<br>
created by the NCAR CAM model. I have tried everything and I can't get it to<br>
work.<br>
sdfopen doesn't work because it has a 365 day calendar. So, I tried xdfopen<br>
with a model descriptor file that looks like this (test.ctl)<br>
<br>
DSET ^tiltedheat_daily_1980_1997_FLNT_anom.nc<br>
TITLE This is only a test<br>
UNDEF -999<br>
XDEF lon 144 LINEAR 0.0 2.5<br>
YDEF lat 96 LINEAR -90. 1.9<br>
TDEF 6206 LINEAR 00Z1jan1980 1dy<br>
VARS 1<br>
OLR=>FLNT_anom 0 x,y OLR<br>
ENDVARS<br>
<br>
-----------------------------------------------------------<br>
<br>
The ncdump -h output for this file looks like this:<br>
<br>
netcdf tiltedheat_daily_1980_1997_FLNT_anom {<br>
dimensions:<br>
time = UNLIMITED ; // (6206 currently)<br>
lat = 38 ;<br>
lon = 144 ;<br>
variables:<br>
double time(time) ;<br>
time:long_name = "time" ;<br>
time:units = "days since 1980-01-01 00:00:00" ;<br>
time:calendar = "noleap" ;<br>
time:bounds = "time_bnds" ;<br>
double lat(lat) ;<br>
lat:long_name = "latitude" ;<br>
lat:units = "degrees_north" ;<br>
double lon(lon) ;<br>
lon:long_name = "longitude" ;<br>
lon:units = "degrees_east" ;<br>
float FLNT_anom(time, lat, lon) ;<br>
FLNT_anom:_FillValue = -999.f ;<br>
FLNT_anom:long_name = "OLR Anomalies from Raw Daily<br>
Climatology" ;<br>
FLNT_anom:units = "W/m2" ;<br>
float FLNT_anom_sm(time, lat, lon) ;<br>
FLNT_anom_sm:_FillValue = -999.f ;<br>
FLNT_anom_sm:long_name = "FLNT Anomalies from Smooth Daily<br>
Climatology" ;<br>
FLNT_anom_sm:units = "W/m2" ;<br>
<br>
// global attributes:<br>
:creation_date = "Wed Sep 5 13:44:55 CDT 2012" ;<br>
:title = "FLNT: Daily Anomalies: 1980-1997" ; }<br>
<br>
----------------------------------------------------<br>
<br>
The error I keep getting when I type "open test.ctl" is:<br>
<br>
Scanning description file: test.ctl<br>
Open Error: Missing or invalid dimension size.<br>
--> The invalid description file record is:<br>
--> XDEF lon 144 LINEAR 0.0 2.5<br>
The data file was not opened.<br>
<br>
<br>
What is wrong with the xdef line? it seems so basic to implement, but it<br>
won't work.<br>
<br>
any help that anyone has would be much appreciated,<br>
<br>
thanks,<br>
