questions about NCEPLIBS-sigio - should it be deprecated, who manages it, what software uses it? #136

Closed edwardhartnett closed 3 years ago

edwardhartnett commented 3 years ago

The NCEPLIBS-sigio package is just two Fortran code files. Does it really need its own library for this? Can't we combine this with one of the other io libraries?

edwardhartnett commented 3 years ago

OK, we'll leave this for this refactor...

Discussed this with Kyle and Hang and this code is needed and will continue to be needed.

Who is code manager for this repo? @kgerheiser is it you?

Do we have an idea where the sigio code is used?

edwardhartnett commented 3 years ago

Also, we say in the README:

Does something with Spectral Coefficients.

Can we be more specific? Do we even know? ;-)

edwardhartnett commented 3 years ago

OK, we now say this in the readme:

This library provides an Application Program Interface for performing I/O on the sigma restart file of the global spectral model. Functions include opening, reading, writing, and closing as well as allocating and deallocating data buffers used in the transfers. The I/O performed here is sequential. The transfers are limited to header records or data records.

Was the global spectral model part of the GFS? Is this restart file still used?

GeorgeGayno-NOAA commented 3 years ago

chgres_cube (of the UFS_UTILS repo) uses the sigio library. It is used to process restart files from the old spectral model (GFS v13 and earlier - prior to Jul 2017). So we need to keep it.

@GeorgeGayno-NOAA should you or @kgerheiser be the code manager here?
