UKCA & UMUI Tutorials

UKCA & UMUI Tutorials for UM8.2

Do NOT use the UKCA Tutoral jobs for scientific studies. They are designed to be used as training aids.

The following tutorials will teach you how to use various aspects of UKCA, and the parts of the UMUI (Unified Model User Interface) that are specific to UKCA.

Before you begin this tutorial you should first get a PUMA and a HECToR or MONSooN account (see Getting_Started_with_UKCA) and have completed the NCAS-CMS UM FCM Tutorial.

The topics covered in this tutorial are:

General use of the UMUI and UKCA:

1. Exploring the UMUI
2. Running existing UKCA Job
3. What is STASH?

UKCA Chemistry Tutorials

Adding new chemical tracers

1. Adding new emissions
2. Adding new chemical reactions
3. Adding dry deposition of chemical species
4. Adding wet deposition of chemical species
5. Adding new UKCA diagnostics

UKCA is not one particular chemistry scheme, but is in fact a framework for adding a chemistry scheme to the UM. Although in this tutorial you will adapt an exisiting scheme, you could extend this to replacing all tracers and reactions and add in a completely different scheme. This tutorial can be run on both HECToR and MONSooN. The HECToR UMUI experiment is xxxx, and the MONSooN experiment is xxxx. This tutorial is based on UM8.2. While some aspects of the UM and UMUI will be different from the version of the UM you will be using, many things are the same. The UKCA source code at UM8.2 is very similar to that at UM7.3. More detailed information on UKCA can be found in the UKCA documentation paper for vn8.2 of the MetUM . You will also find the NCAS-CMS pages very useful: cms.ncas.ac.uk.
