You should set your dimension to something else to avoid having half-index values or decrease your x-dimension environment boundaries by 1.0 points each ('set x 361 1080'). Either that, or adjust the XDEF entry in your control file to match what you're setting in your dimension environment.<br>

Dear Users,<br>
<br>
I am trying to convert a binary file to a netCDF4<br>
file using sdfwrite. I have a control file<br>
which looks like:<br>
<br>
DSET tsfc_3hr_%y4%m2.dat<br>
OPTIONS TEMPLATE<br>
UNDEF -1000.<br>
XDEF 720 LINEAR -179.75 0.50<br>
YDEF 360 LINEAR -89.75 0.50<br>
ZDEF 1 LEVELS 1000.<br>
TDEF 8768 LINEAR 00z01Jan2007 3hr<br>
VARS 1<br>
tsfc 0 99<br>
ENDVARS<br>
<br>
When I do 'q dims', I get:<br>
Default file number is: 1<br>
X is varying Lon = 0 to 360 X = 360.5 to 1080.5<br>
Y is varying Lat = -89.75 to 89.75 Y = 1 to 360<br>
Z is fixed Lev = 1000 Z = 1<br>
T is fixed Time = 00Z01JAN2007 T = 1<br>
E is fixed Ens = 1 E = 1<br>
<br>
So, lon should have 720 points, lat should<br>
have 180 points, and for a 30 day month, there<br>
should be 248 time steps.<br>
<br>
However, when I use the sdfwrite command:<br>
<br>
open tsfc_3hr.ctl<br>
set time 00Z01Jan2007 21Z30Jan2007<br>
define tsfc = tsfc<br>
set sdfwrite -flt -nc4 <tsfc_file>.nc4<br>
sdfwrite tsfc<br>
<br>
I get metadata that has the wrong lon<br>
dimension:<br>
netcdf tsfc_3hr_Aug1995 {<br>
dimensions:<br>
lon = 722 ;<br>
lat = 360 ;<br>
time = 248 ;<br>
(etc)<br>
<br>
So, my questions are, why is the lon dimension<br>
wrong and how do I fix this?<br>
<br>
Thanks,<br>
Roz<br>
