PUMA and HECToR/MONsooN
Before you begin this tutorial you should first get a PUMA and a HECToR or MONSooN account as the UKCA Tutorial is based around jobs which run on these supercomputers, using PUMA to submit them.
Further information about how to apply for these account can be found on the Getting Started with UKCA page.
UM Training and the FCM Tutorial
There is some information about the UM here:
http://cms.ncas.ac.uk/wiki/UmTraining
You must also have completed the NCAS-CMS UM FCM Tutorial. This tutorial assumes that you have had some experience in using the UM, and know how to copy an existing job to your account and run it.
If you have never used the UM before you should also view the NCAS-CMS UM Training pages, which has a basic introduction to the UMUI.
Archiving
By default the UKCA Tutorial jobs are set to archive data to
/work/n02/n02/userid/um/jobid/archive/
on HECToR, and to
/nerc/ukca/userid/jobid/
on MONSooN (if you are not in the ukca project group you will need to set your project group here).
This will be known as your archive directory throughout the rest of this tutorial.
Note: If you have made some changes to a job and resubmit it, the files in your archive directory will not be over-written. You will need to either delete these files, or move this directory before starting your job again, e.g.
On HECToR cd into your
/work/n02/n02/userid/um/jobid/
directory and do
mv archive archive.old
and on MONSooN cd into your
/nerc/group/userid/
and do
mv jobid jobid.old
etc. This now means that when your job runs new output will be copied to the archive directory, which is created by the UM if it does not exist.
Archiving is controlled in the UMUI in the Model Selection → Post Processing → Main Switch + General Questions panel.
Structure
UKCA Chemistry Tutorials
These Tutorials are actually one large problem which someone who uses UKCA may be required to do: add some tracers, reactions, deposition, and diagnostics. To make this problem more manageable it has broken down into a series of small tasks which you will be asked to complete. Each Tutorial explains how to make the necessary changes (in general terms), and then you will be asked to make the required changes to your UKCA job.
To accompany each Task which requires UMUI or UKCA code changes, there are worked solutions (held in the same UMUI Experiment as the original Tutorial Base Job) along with sample output and a wiki page detailing the changes in full. If at any point you have difficulty completing one of the Tasks you can take a copy of the worked solution job and carry on from there.
