"One time step" issue in ensemble initialization step #84

Closed delippi closed 5 months ago

delippi commented 9 months ago

DO_ENSINIT=TRUE enables the 1 time step part of the workflow. The only purpose of this is to "convert" cold starts from chgres_cube into warm starts by running the model for a single time step. This is done because warm start/restarts are needed for the recentering.

The problem: We run the model for 1 time step (36s) and then use that t+36s restart file as initial conditions starting at t+0s by resetting the time step back to zero by modifying coupler.res replacing the 36s information with 0s.

The solution: Eliminate the ENSINIT step completely and replace it with the blending tools that converts cold starts to warm starts.

Should be invoked with v0.7.7 upgrade.

I think this one is complete. @delippi can you confirm?

@MatthewPyle-NOAA @JacobCarley-NOAA , yes this one is complete.
