I changed my mercator_test.ctl, but no success for the moment.<br>
Please find attached the new configuration.<br>

The dimensions of your grid (as seen in the ncdump output) are the
following: <br>
dimensions:
<br>
depth = 8 ;
<br>
latitude = 129 ;
<br>
longitude = 341 ;
<br>
<br>
But in your descriptor file, you've got: <br>
XDEF 340 LINEAR -6 0.125
<br>
YDEF 128 LINEAR 30 0.125
<br>
ZDEF 8 LEVELS 5 30 50 100 200 500 1000 2000
<br>
<br>
The sizes of the dimensions must match exactly. Change your XDEF to
341 and your YDEF to 129. Also, your variable declarations in your
descriptor file are incorrect. The units field (e.g. "x,y,z,t") must
describe the 'shape' of the variable as given in ncdump -- the order
of the dimensions must match exactly. For example, in the ncdump
output, the variable "u" varies in depth, latitude, and longitude,
whereas the variable "emp" only varies in 2 dimensions: <br>
float u(depth, latitude, longitude) ;
<br>
float emp(latitude, longitude) ;
<br>
These should translate to a variable declarations like this (note the
2nd field repeats the number of zlevs): <br>
u 8 z,y,x zonal velocity [m/s]
<br>
emp 0 y,x water flux [Kg/m2/s]
<br>
None of the variables in your file are time-dependent, so don't
include "t" in your variable declaraion. <br>
<br>
These changes should fix your problems. <br>
