| run_henk_mixedbc | 0075-0327 | High resolution present day simulation with an extra 'implied flux' term instead of 'restoring under ice’ for SST and SSS. This so called ‘mixed boundary conditions’ simulation is forced with the default prescribed present day atmospheric state with a repeating annual cycle and observed river simulation-off fields but as mentioned also forced with an extra ‘implied_flux’ term. To determine this term we ran the original control simulation ‘control_mat’ from year 75 for 5 years with the ‘restoring under ice’ term on for both SST and SSS and then diagnosed the implied flux. We then made a monthly 5-year average of this and used this as the extra implied_flux term and which was put in the SHF and SFWF forcing files. |
| run_henk_mixedbc_extravars_viebahn | 0276-0327 | Continuation of run_henk_mixedbc from year 276 but now outputting the following extra variables for collegue Jan Viebahn: WVEL,Q,PD,PD2,PDW,WPD,UVEL2,VVEL2,KE,UTAUX,VTAUY,STFRHO,SSFRHO,EVAPRHO,PRECIPRHO,SWRESTRHO,SSRESTRHO,RUNOFFRHO,ALPHA01,BETA01. For this purpose the code files advection.F90 and baroclinic.F90 needed to be modified. |
| run_henk_mixedbc_extravars_nooteboom | 0321-0325 | Continuation of run_henk_mixedbc_extravars_viebahn from year 321-325 but now outputting only daily 3D fields UVEL, VVEL and WVEL and 2d fields TEMP_5m, TEMP_15m, SALT_5m, SALT_15m and SSH. This simulation was done for Peter Nooteboom |
| prod_run3_0.5Sv | 0075-0175 | High resolution present day simulation with a 0.5Sv freshwater flux around Greenland. This Simulation has the same forcings as ‘run_henk_mixedbc’ but in this simulation 0.5 Sv of freshwater was dumped, by enhanced runoff around Greenland. The runoff is distributed in a realistic spatial and temporal pattern around the coast of Greenland inspired by studies of present-day runoff from the Greenland Ice Sheet. |
| prod_run3_0.5Sv_restarted_mixedbc | 0120-0170 | Restart from the (at that time) latest restartfiles (0120-01) of the high resolution 0.5Sv Greenland simulation (prod_run3_0.5Sv) but now with the mixed bc conditions (same as run_henk_mixedbc) to see how quickly the MOC recovers. |
| prod_run3_0.5Sv_restarted_reverse | 0120-0152 | Restart from the (at that time) latest restartfiles (0120-01) of the high resolution 0.5Sv Greenland simulation (prod_run3_0.5Sv) but now with a negative freshwater perturbation added meaning that we are basically adding salt (0.5 Sv) instead of freshwater around the coast of Greenland. The run is used to study the recovery of the MOC. |
| real_forcing | 0075-0133 | High resolution present day simulation similar to run_henk_mixedbc but with only difference that we used a realistic windstress forcing taken from the CORE dataset of years 1949- 2006. These windstress fields were downloaded from: https://climatedataguide.ucar.edu/climate-data/large-yeager-air-sea-surface-flux-corev2-1949-2006 and interpolated to the POP grid. However with these wind stresses the model often crashed because of too high velocity katabatic winds mainly on Greenland but also elsewhere in the arctic region. Decreasing the timestep did not help so we decided to use the wind stress forcing of ‘run_henk_mixedbc’ in the Arctic region above 65N (j=2000) and the CORE windstress for the latitudes on and below 65N. To avoid a sudden jump of wind stress at 65N we tapered the two wind stress fields into each other (in the region j=1900:2100 with a special Ferret function). This avoids any strange circulation that might occur as a result of the jump. After this the model ran without problems. |

0300-0326 | Set of 5 ensemble members 001 until 005 restarted respectively from the december restartfiles of years 300, 305, 310, 315 and 320 of the control simulation 'run_henk_mixedbc' . Each simulation is forced with 23 TipJet (TJ) events in December-March and a Non-Zero mean, meaning that there is 0 extra forcing on non-TipJet days and on each day in the months April-November. Each member ran for 6 modelyears, the first 5 years with the TJ forcing and the last year with just the default present day forcing and without TJs |

|---|---|---|
| x1_SAMOC_flux | 0075-1693 | Low resolution present day control run with year 2000 initial conditions and atmospheric forcing (= equivalent of the high resolution case ‘run_henk_mixedbc’ but now for 1 degree case) |
| x1_SAMOC_flux_1yr_with_dailies | 1690 | x1_SAMOC_flux restarted in year 1690 and run for 1 year with daily output (netcdf) |
| x1_run_clim_closeddrake | 0575-1575 | Low resolution present day run which is the same as x1_SAMOC_flux but now with a closed Drake Passage. This run was started from the 0575-01 restart files of run x1_SAMOC_flux |
| x1_run_clim_closeddrake_extra_BOLUS | 1579 | This is x1_run_clim_closeddrake restarted in year 1579 and now writing out extra daily bolus fields for one year |
| x1_SAMOC_greenland0.5Sv | 0575-1575 | Low resolution present day run with 0.5 Sv hosing around Greenland. This run was started from the 0575-01 restart files of run x1_SAMOC_flux with same initial conditions and atmospheric forcings but in this run 0.5 Sv of freshwater was dumped (by enhanced run off) around Greenland. The runoff is distributed in a realistic spatial and temporal pattern around the coast of Greenland inspired by studies of present-day runoff from the Greenland Ice Sheet. |
| x1_SAMOC_greenland0.5Sv_restarted_reverse | 0620-0700 | This run was started from the 0620-01 restart files of run x1_SAMOC_greenland0.5Sv but now with a negative 0.5 Sv freshwater forcing around Greenland (negative salt) |
| x1_SAMOC_greenland0.5Sv_restarted_nohosing | 1575-2605 0620-0710 |
This run was started from the 1575-01 restart files of run x1_SAMOC_greenland0.5Sv but now without the 0.5Sv hosing around Greenland to test how quickly the MOC will recover. Later we also restarted it in year 620, to compare with x1_SAMOC_greenland0.5Sv_restarted_reverse |
