UKCA Chemistry and Aerosol Tutorials at vn10.4

When using the UM, it is likely that you will want to add new diagnostics, and we will cover writing out chemical fluxes in a later tutorial. Here we will cover selecting new diagnostics in STASH.

Task 3.1: add new output

TASK 3.1: Output the daily-mean UKCA ozone field to the UPK, and then add-in the same diagnostic on pressure levels using the DP36CCM domain.

Hint
You will need to remember to run the TidyStashTransform macro once you have added the diagnostics in the STASH panel. You will also need to set the `l_ukca_chem_plev` logical to true.

In the following page you will learn more about how the Unified Model's output is organised and managed. You should use this information to complete the task above. A worked solution is provided at the end of the tutorial.

Add in

UKCA Ozone on model theta levels daily mean to UPK
Turn on pressure level diagnostics in UKCA panel (need for this will be retired at a later version)
UKCA Ozone on pressure levels (DP36CCM) daily mean to UPK
Heaviside Function on same pressure levels from s50 daily mean to UPK
Change periodic re-init of UPK (pp10) to 1 day from 90 (not needed to fit files, but better for file management)

Remember to run the stashindicies.TidyStashTransform macro!

See u-ag308@21303
