Exploring the UMUI
Getting hold of an existing UM-UKCA job
Before you can start using UKCA (and the UM generally), you first need to copy a UM or UKCA job from somewhere. You may be given a job from someone for a specific purpose, or you may just copy a standard job. In the UMUI there are two repositories of standard jobs, under the umui and ukca UMUI users. The umui user contains a series of standard jobs provided and maintained by NCAS-CMS. The ukca user contains jobs provided by the UKCA team.
Make a new experiment and take a copy of the UKCA Tutorial Base Job, filter for the ukca user and choose the correct experiment for the machine that you will be running on (HECToR: xxxx, MONSooN: xxxx). Select the a job, labeled Tutorial Base UM-UKCA Job and copy this one to your own experiment.
More details on how to copy UMUI jobs can be found in the NCAS-CMS Introduction to the UMUI tutorial video.
What is the UMUI
The UMUI is the Unified Model User Interface. It is used to configure UM model options and parameters, and, for climate simulations, is also used to manage submission of the job to the supercomputer. As well as inserting values into the Fortran namelists used by the model, it also checks the logical of those choices. It is also possible to add variables into the namelists directly using hand-edits, which will be discussed in more detail in the adding new chemical tracers tutorial.
The UMUI itself is rather complicated, with many different panels, but no search function. Without experience it can be difficult to find which panels are useful. While this tutorial will go through many of the panels that are useful or relevant to using UKCA, it is recommended that you take some time to familiarise yourself generally with the UMUI.
The UMUI: Quick Reference
The Interface Bar
When you start-up the UMUI you will be given a list of all your experiments. Along the top of this window there is a bar which gives a number of useful options
Search
The
Search -> Filter...
option is very useful. This allows you to filter UMUI jobs by user, experiment ID, version etc. You will mostly be copying a job from another user (as you have done for this tutorial) and so will need to use the search function for this.
