XIOS online weighted average not working properly

[joakim]

Hi

I'm running NEMO3.6 (rev 4672) and have XIOS rev 484, both compiled using ifort 14.0.1, netcdf 4.3.0 and hdf5 1.8.11.
I'm using non linear free surface so temperature and salinity are in fact multiplied by cell thickness in output.

I've therefore put
<field field_ref="toce" name="potemp" long_name="sea_water_potential_temperature" operation="instant" freq_op="1m"> @toce / @cellthc </field>
<field field_ref="soce" name="salin" long_name="sea_water_salinity" operation="instant" freq_op="1m"> @soce / @cellthc </field>
in my iodef.xml. I want XIOS to divide temperature by cell thickness every time step and then write the monthly mean.

This works fine except the first month. The file can’t be opened with ncview, but looks fine with ncdump.
I think it’s because XIOS changes the time variable from “time_centered” to “time_instant” and the variable "time_instant" is empty in the first file.
I’m guessing this is a bug in XIOS.
Does anyone know of any way to get around this issue?

Regards
Joakim
