Why did the grid be set to two forms with a and b suffixes in the source code of gen_domain.F90

Dear scientists of NCRA

Sorry to bother you, when I read the code of gen_domain.F90 in tools/ folder, something makes me confused. I want to learn "Why did the grid be set to two forms with a and b suffixes in the source code of gen_domain.F90"?

looking forward your reply, and thank you every much.

Hi Dayon,

The other mapping tools typically name the grids _src (to signify the source grid, or where data is being mapped from) and _dst (to signify the destination grid, or where data is being mapped to). However, gen_domain generates output files on both grids (two on the atmosphere grid and one on the ocean grid) so the source / destination labels don't make sense. Therefore we differentiate between them by naming them _a (ocean) and _b (atmosphere).
