==Results (MONSooN)==

===MOOSE===

All results from this run were saved to MOOSE, and can be found at <code>moose:/crum/xkjgj</code>. As well as the standard pp-output, monthly, seasonal, and annual supermeans were created and are also available in the <code>am5.pp</code> directory.

Running the command <code>moo ls -l moose:/crum/xkjgj</code> gives

'''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 <code>--project-owner=project-ukca</code>. This can be done after the job has started running. The archiving intelligently knows which files need archiving through the use of files named <code>archive_XXXXXX.do</code>. The files also control the deleting of files and dumps once they have been archived or are no longer needed.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 <code>/projects</code> 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 When it does you will find that, while the climate mean files and dumps have been archived, the last files in the e.g. <code>*.pa*</code> or <code>*.pb*</code> streams etc will not have been. You will need to archive these manually by, e.g.

 moo put -f -vv -c=umpp '''<span style="color:blue">jobid</span>a.p<span style="color:red">z</span><span style="color:green">YYYYmmm</span>''' moose:/crum/'''<span style="color:blue">jobid</span>'''/'''ap<span style="color:red">z</span>.pp'''/'''<span style="color:blue">jobid</span>a.p<span style="color:red">z</span><span style="color:green">YYYYmmm</span>.pp'''

Where the <code>-c=umpp</code> converts the files from 64-bit fieldsfiles to 32-bit pp-files. Remember to put the <code>.pp</code> 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 [[Vn8.4_GA4.0_Release_Candidate:_RC6.0#Non-uniform_polar_values_for_air_potential_temperature_(theta)|problems with the polar rows found in RC6.0]]. The tracer fields were initialised from output from Graham Mann's RC6.1 job <code>xkaxr</code>, 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
