I noticed that nobody gave you an answer, so I thought I would give it a
Within WRF, Noah LSM does not need continuous soil temperature and moisture
data. real.exe creates data in the wrfinput_d0? file for initial conditions,
but from there the LSMs models soil temperature and moisture themselves
based on what the atmosphere does, and which in turn affects the atmosphere,
of course. Even if you use the sst update option, there is no soil moisture
or temperature data in the wrflowinp_d0? files. The WPS process uses a lot
of variables, but some only make it into the initial conditions, not ongoing
Regarding the intermediate format - the users guide gives a description of
the format, and it also mentions that the source code
metgrid/src/write_met_module.F90 can be used as a starting point. You
probably knew that already. The netCDF folks at unidata(?) (Google netCDF)
have library interfaces for several programming languages so you might find
one that fits your programming experience. I have not written intermediate
format myself, so I can't help with any source code. Sorry.
