UKCA Chemistry and Aerosol Tutorial 10

Back to UKCA Chemistry and Aerosol Tutorials

What you will learn in this Tutorial

In this tutorial you will learn about how to run the GLOMAP-mode aerosol module with a different configuration re: which components are included in each mode. You will run a copy of the standard UKCA job which tracks organic carbon in two separate components -- one for the primary (emitted) organic carbon and one for secondary organic carbon formed following oxidation in the atmosphere.

Task 10.1: Understand how the GLOMAP aerosol module tracks aerosol species and modes

TASK 10.1: Read section 12 (page 32) of the UKCA UMDP and refer to Tables 18, 19 and 20 on pageof the reaction ${\textrm {ALICE}}+{\textrm {OH}}\longrightarrow {\textrm {BOB}}+{\textrm {SEC\_ORG}}$ to STASH code 34461, the dry deposition of ALICE to STASH code 34462, and the wet deposition of BOB to 34463. They should be outputted as a daily mean to the pa/UPA stream.

Task 10.2: Run the copy of the standard UKCA job tracking two OC components in the GLOMAP modes

Take a copy of the XXXXX job from the Tutorial experiment labelled two-component OC job and submit it for the 2-day run. Note that this uses the same branch as the standard job but allows you to run either the standard GLOMAP configuration in UKCA (MS2) or the two-component OC configuration (MS4).

Task 10.3 Examine the simulated organic carbon in each mode in original and two-component OC configuration

We recommend you use xconv for this task.---- Written by Graham Mann 2014
