#241 | Fixed | Updated 4DVar surface forcing adjustment | ||
Description |
The 4DVar adjustment of surface forcing (ADJUST_WSTRESS and ADJUST_STFLUX) was revisited in view of the new IS4DVAR algorithm with preconditioning. To avoid confussion, the surface fluxes in output tangent linead and adjoint NetCDF files are written as kinematic fluxes (m2/s2 for stress and Celsius m/s heat flux). However, the same variables associated with the nonlinear model are scaled to Pa and W/m2, respectively. Additional logic is added when the surface forcing is computed using the BULK_FLUXES option. In this case, the fields are convolved since the minimization is done in v-space. The bacground cost function term (Jb) was corrected to add contributions from all previous outer loops. Many thanks to Andy Moore for looking and testing this option in the new IS4DVAR algorithm. |

#242 | Done | Updated weak constraint 4DVAR impulse forcing | ||
Description |
Updated both weak constraint drivers W4DVAR and W4DPSAS conjugate gradient algorithm (congrad.F) and allowed full weak constraint. Added new code to allow the time intepolation of the impulse forcing that is used in the outer loop by the representer model. We also corrected a couple of critical bugs in W4DVAR. Many thanks to Andy Moore for finding these bugs. |
