Hi Jon,
This is may be not what you expect, but we are doing it "manually" with
ncml, as in the following piece of xml. There are 4 different variables
in 2 different files per time step. We need to rename on the variable
in each file (PCTVAR) because the are identically named in the different
files:
<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";>
<aggregation dimName="time" type="joinExisting">
<variableAgg name="PSAL"/>
<variableAgg name="PSAL_PCTVAR"/>
<variableAgg name="TEMP"/>
<variableAgg name="TEMP_PCTVAR"/>
<netcdf coordValue="14624.0"><!-- timestep 1 -->
<aggregation dimName="time" type="union">
<netcdf
location="file:///home4/garo/oo/coriolis/co052004/CORA-GLOBAL-03.4/OA/field/1990/OA_CORA3.4_19900115_fld_PSAL.nc"
coordValue="14624.0">
<variable name="PSAL_PCTVAR" orgName="PCTVAR"/>
</netcdf>
<netcdf
location="file:///home4/garo/oo/coriolis/co052004/CORA-GLOBAL-03.4/OA/field/1990/OA_CORA3.4_19900115_fld_TEMP.nc"
coordValue="14624.0">
<variable name="TEMP_PCTVAR" orgName="PCTVAR"/>
</netcdf>
</aggregation>
</netcdf>
<netcdf coordValue="14655.0"><!-- timestep 2 -->
<aggregation dimName="time" type="union">
<netcdf

coordValue="14655.0">
<variable name="PSAL_PCTVAR" orgName="PCTVAR"/>
</netcdf>
<netcdf

coordValue="14655.0">
<variable name="TEMP_PCTVAR" orgName="PCTVAR"/>
</netcdf>
</aggregation>
</netcdf>
<netcdf coordValue="14683.0"><!-- timestep 3 -->
<aggregation dimName="time" type="union">

coordValue="14683.0">
<variable name="TEMP_PCTVAR" orgName="PCTVAR"/>
</netcdf>
</aggregation>
</netcdf>

cheers,
Thomas

Hi,
I have a dataset consisting of 4 variables, each recorded on around 1000
timesteps. Unfortunately each variable and each timestep is provided as a
separate NetCDF file, so I have about 4000 files. Ideally I'd like to create a
single dataset aggregating all of these variables and timesteps. How can I
structure my THREDDS catalog to do this?
(It's not a forecast model so there are no overlapping times, so I'd like to
avoid the FMRC aggregation type if possible.)
Cheers,
Jon
