- Experiment id: ens_both. EDA+SV+SPPT+SKEB : Includes initial data uncertainty (EDA, SV) and model uncertainty (SPPT, SKEB)
- Experiment id: ens_initial. EDA+SV only : Includes only initial data uncertainty
- Experiment id: ens_model. SPPT+SKEB only : Includes model uncertainty only
- Experiment id: ens_oifs. SPPT+SKEB only, class ensemble : this is the result of the previous task using the ensemble run by the class
These are at T319 with start dates: 24/25/26/27 Oct at 00UTC for a forecast length of 5 days with 3hrly output.
The aim of this exercise is to use the same visualisation and investigation as in the previous exercises to understand the impact the different types of uncertainty make on the forecast.

The different macros available for this exercise are very similar to those in previous exercises.
For this exercise, use the icons in the row labelled 'Experiments'. These work in a similar way to the previous exercises. ens_exps_rmse.mv : this will produce RMSE plumes for all the above experiments and the operational ensemble. ens_exps_to_an.mv : this produces 4 plots showing the ensemble spread from the OpenIFS experiments compared to the analysis. ens_exps_to_an_spag.mv : this will produce spaghetti maps for a particular parameter contour value compared to the analysis. ens_part_to_all.mv : this allows the spread & mean of a subset of the ensemble members to be compared to the whole ensemble.Note that the larger geographical area, mapType=1, will only work for MSLP due to data volume restrictions. |

For these tasks the Metview icons in the row labelled 'ENS' can also be used to plot the different experiments (e.g. stamp plots). Please see the comments in those macros for more details of how to select the different OpenIFS experiments. Remember that you can make copies of the icons to keep your changes. |
