John,
I have discovered another point of conflict to my proposal of permuting
run and time dimensions an is in :
ucar.nc2.dt.grid.GridCoordSys.makeTimeAxisForRun(int)
and more precisely tAxis.slice, which is assumint the runtime dimension
in the 1st position
private CoordinateAxis1DTime makeTimeAxisForRun(int run_index) {
VariableDS section;
try {
section = (VariableDS) tAxis.slice(0, run_index);
return CoordinateAxis1DTime.factory(ds, section, null);
} catch (InvalidRangeException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
A.

Dear John,
(I'm using the netcdf-java 4.3.15)
As you can see in the attached ncml,I'm defining a RunTime dimension
in the Total_precipitation_surface inner than the time dimension. I'm
doing this because I need to do the outer aggregation for the forecast
time dimension. Also the time variable is been aggregated.
The problem is that the Total_precipitation_surface variable it's no
been recognized as a Grid data type. If I permute dimensions on the
time variable then the variable is recognized as Grid datatype.
This is right? or I'm forced to define as first dimension the RunTime
axis on the time 2D coordinated axis?
Looking at:
ucar.nc2.dt.grid.GridCoordSys.isGridCoordSys(Formatter,
CoordinateSystem, VariableEnhanced)
which it appears to be the responsible for deciding if a Variable is a
Grid datatype
It appears that it could be easily fixed if we modified this part:
if (!rt1D.getDimension(0).equals(t.getDimension(0))) {
if (sbuff != null) {
sbuff.format("%s: Time axis must use RunTime dimension%n",
cs.getName());
}
return false;
}
coding also the check for the 2nd dimension:
if (!rt1D.getDimension(0).equals(t.getDimension(0)) &&
!rt1D.getDimension(0).equals(t.getDimension(1))) {
if (sbuff != null) {
sbuff.format("%s: Time axis must use RunTime dimension%n",
cs.getName());
}
return false;
}
It's correct?
Antonio
