Functionality
Base Model (MONSooN)
The base atmosphere model used here is the GA4.0 configuration. More information on GA4.0 development can be found on Global Atmosphere 4.0/Global Land 4.0 documentation pages (password required). A GMD paper documenting this model is also available.
The configuration is based on the Met Office job anenj
(via MONSooN job xhmaj
) which is derived from amche

Results (MONSooN)
MOOSE
All results from this run were saved to MOOSE, and can be found at moose:/crum/xkjgj
. As well as the standard pp-output, monthly, seasonal, and annual supermeans were created from the last 5 years and are also available in the am5.pp
directory.
Running the command moo ls -l moose:/crum/xkjgj

Further information on how to use MOOSE can be found on the collaboration twiki.
Note: If you take a copy of this job and run it, you must first manually make the MOOSE set to hold the data in the archive. This is done by
moo mkset --project-owner=project-YOUR_MONSooN_PROJECT -v moose:/crum/jobid
For instance, if you were in the UKCA project you would have --project-owner=project-ukca
. This can be done after the job has started running. The archiving intelligently knows which files need archiving through the use of files named archive_XXXXXX.do
. The files also control the deleting of files and dumps once they have been archived or are no longer needed. If, for some reason, the files cannot be archived (e.g. MOOSE is down or the set has not yet been made) then the files will not be deleted. They will continue being generated and existing on the /projects
disk until they can be archived.
You should not need to do anything with the fieldsfiles until the whole simulation has been completed (in this case, the whole 15-years). When it does you will find that, while the climate mean files and dumps have been archived, the last files in the e.g. *.pa*
or *.pb*
streams etc will not have been. You will need to archive these manually by, e.g.
moo put -f -vv -c=umpp jobida.pzYYYYmmm moose:/crum/jobid/apz.pp/jobida.pzYYYYmmm.pp
Where the -c=umpp
converts the files from 64-bit fieldsfiles to 32-bit pp-files. Remember to put the .pp
at the end of the name of the file in the set on MOOSE.
Evaluation Suite Output (MONSooN)
This job was run for 15 years, and had to be initialised using a new start-dump due to the problems with the polar rows found in RC6.0. The tracer fields were initialised from output from Graham Mann's RC6.1 job xkaxr
, taken from the 10-year September dump.
A set of standard results from a mean of the last 5 years of the 15-year run, as well as from each of the last 5 of the 15 years can be found in the following documents.
These were generated from the UKCA Evaluation Suite available on the MONSooN post-processor.

Lightning NOx
The average annual Lightning NOx emitted is 4.04299 Tg(N)/year over the the last 5 years of the 15-year simulation.
The lightning NOx emitted in each of the last 5 individual years of the run is:
- year 11 3.97454 Tg(N)/year
- year 12 4.08936 Tg(N)/year
- year 13 4.04931 Tg(N)/year
