Hi Ekin,

if I could give you some advice based on having used netcdf for many
years, it would be to avoid going the route you seem to have taken
with using fortran compound types. The reason being that I think you
will find that it greatly reduces the ease, speed, and portability of
your output files across different applications, since support for
compound types in applications is not well advanced yet. And
presumably easy interoperability is the whole reason you are using
netcdf in the first place.

Instead, the best solution is to keep things simple. Just name your
output variables "ep_data_biomass" and "ms_data_biomass" and write
them as regular variables, not compound types. Then, no namespace
collision.

Regards,

--Dave
