Description
This update adds the mixed-resolution split 4D-Var capability to run the outer loops (Background and Analysis phases) at a higher grid resolution than the inner loops (Increment phase). For more information, please check:
https://github.com/myroms/roms/pull/55
A test case for the U.S. East Coast (USEC) with outer loops at 3km resolution and inner loops at 6km resolution is provided. Please check the following documentation and instructions:
https://github.com/myroms/roms_test/blob/main/USEC/RBL4DVAR_mixres/Readme.md
This complex algorithm is intended for expert users of ROMS 4D-Var algorithms. The devil is in the details, and users need to pay acute attention to every step in the configuration.
Good luck!
