* '''Question:''' Should ALL schemes using the '''''backward Euler solver''''' be proposed for redundancy?
−
:: '''ALL''' to do a quick check (2 weeks deadline)
  
−
:: '''LA''' to finish off by looking through code and opening tickets for all things that have not been done.
  
   
  +
It was agreed that this should be a long-term aim, targeting offline-oxidants first. OpenMP work will proceed around the column-call to ASAD to speed this up and make it competitive.
−
=== <code>rafeps</code> ===
  
   
  +
MS has OpenMP code that has not been lodged, for Fast-JX and current ukca_chemistry_ctl routine (using lat/lon slice in the call to ASAD).
−
'''<code>rafeps</code>''' is set in UKCA like this:
  
   
  +
'''new action:''' FOC to arrange meeting between FOC, MR, MS, LA (& others who are interested) to sit down and decide a plan to move forward with OpenMP work, before new person starts.

  +
'''new action:''' LA to update [[Redundant code]] tables with above information
−
This is rather convoluted! Previously it was found increasing <code>rafeps</code> by ~1.0e50 seemed to improve stability in the TropIsop configuration. There is a ticket open for this ([https://code.metoffice.gov.uk/trac/um/ticket/368 #368] - see also the [[#Open_Bugs|open bugs]] below).

==== Depreciated Code ====
−
Comment from Oliver Wild:
  
   
  +
{| class="wikitable" border = "1px"
−
The intention is that peps is the underflow limit, and that rafeps is a
  
  +
!style="text-align:top;|#
−
minimum of one order of magnitude more than this, just to avoid problems.
  
  +
!style="text-align:top;|Description
−
However, this is a bit slack, as the value of f may be multiplied by numbers
  
  +
!style="text-align:top;|Ticket
−
quite a bit less than one later in the code. So it's better to crank it up
  
  +
!style="text-align:top;|Remarks
−
a bit - the sqrt halves the exponent, so should be sufficient. I hardwire
  
  +
!style="text-align:top;|Status
−
peps to 1.d-200 in my code (substantially more than the underflow limit),
  
  +
!style="text-align:top;|Owner
−
and rafeps is just peps*10.d0. Your value of 3.e-144 is fine.

My feeling is that as long as rafeps is "small", i.e., considerably below

−
any expected mixing ratios in the atmosphere, then all should be fine. By

−
setting zeros to rafeps, you may be adding material to the atmosphere, so
  
−
you don't want to let rafeps get too large - but the principal issue is
  
−
avoiding underflows, or overflows when dividing. I don't think 1.e-100 would
  
−
be any problem. Even at the 1.e-50 level you may still be OK, although this
  
−
scale starts to makes me uncomfortable as errors can build up quickly if left

unchecked.

I would suggest that altering the value of <code>rafeps</code> in itself is fine, although I (LA) would personally not want it to go smaller than 1.0e-100.

−
* StdTrop - '''FOC'''
  
−
* volume_mode - '''AH'''
  
−

−
'''JM''' to check with CJ about the ''Wet oxidation of SO2 in GLOMAP''
  
−  
−
'''ALL''' to note code where there is redundancy

It was also discussed that things like Families chemistry & Impact solver could be removed as well.

==== Code Restructuring (OM) ====
  
−  
−
OM has been considering how best to restructure the chemistry. This proposal will remove all the existing <code>ukca_chem_'''scheme'''.F90</code> routines, and replace them with a single <code>ukca_chem_master.F90</code> routine that contains all the species, reactions, & deposition from all the current schemes, as well as a routine to construct the correct arrays for each scheme in an intelligent way.

There was a question regarding whether or not it would also be possible to have multiple versions of rates defined, to easily allow for running with the old rates, for example, and this would be possible with this method. It should also not break rose-stem for GA7.1+StratTrop so long as the order of reactions is not changed.
  
−  
−
Oliver Wild had commented to FOC that he wondered how well this method would cope with species that are representative of a whole class of species in some schemes, but explicitly considered in others. This shouldn't be a problem however as the schemes, while contained in the same master array, are independent.
  
−  
−
It was suggested that trying RAQ through the symbolic ASAD BE solver would be a good test to compare with the current RAQ BE formulation. It may also be worth removing the 2D dry deposition at the same time as implementing this.
  
   
  +
This code should not be removed for legacy reasons.

MD has a free running TS2000 job, and is adding a nudging job. However, many users are requesting an AMIP job. While aerosol emissions are transient, chemical emissions are decadal means.

−
# UKCA configurations are available across versions with the same science settings (e.g. similar to GA7.1)
  
−
# Regression branches would be provided to allow for bit-comparison between UM versions to allow people to run the same science but at later versions - this would aid people in developing changes for the trunk
  
−
# TS2000 free-running and nudged configurations will be provided and assessed at each UM version, without branches where possible. These will form the basis of the release and evaluation suite output will be provided from each run to allow for comparison to the previous UM version
  
−
# Release jobs will not be updated once they have been released, instead users will be directed to the next model version for bugfixes etc.

=== Targets for vn11.0 (and beyond) (LA) ===
−
* '''CJ:''' ''Water vapour feedback'' - This includes flux calculations of water production and loss available in stash, as well as a diagnostic which gives the change to q calculated at each timestep. ([https://code.metoffice.gov.uk/trac/um/ticket/1646 #1646] & [https://code.metoffice.gov.uk/trac/um/ticket/3123 #3123])
  
−
* '''LA:''' ''Quasi-Newton steps in Newton-Raphson solver'' - speeds up the model by ~2-3%. Will not bit-compare with runs without it however. ([https://code.metoffice.gov.uk/trac/um/ticket/2819 #2819])
  
−
* '''MR:''' ''OpenMP in UKCA_AERO_CTL'' - alternative method for passing array slices to sub processes, e.g. a(:,:,:,mode) had to be re-written a(1,1,1,mode) for the combination of Linux system SPICE and Intel ifort 12. ([https://code.metoffice.gov.uk/trac/um/ticket/1286 #1286] )
  
−
* '''MR:''' ''OpenMP in UKCA_AERO_CTL'' - a bespoke workshare had to be written due to ONE failure in rose stem. The formal method that used the default blocking of data failed. Again Linux and Intel 12. ([https://code.metoffice.gov.uk/trac/um/ticket/1286 #1286] )
  
−
* '''LA:''' 3 new UKCA rose-stem tests were added to the MetO XC40. This tests mirror the ones available on the VM, but run incredibly quickly. One has been added to the <code>xc40_developer</code> group - <code>meto_xc40_n48_ukca_eg_omp_noios_gnu</code>. ([https://code.metoffice.gov.uk/trac/um/ticket/2714 #2714])
  
−
** '''Note:''' On the XC40 the <code>_omp</code> and <code>_noomp</code> jobs do '''not''' bit-compare, whereas they do on the VM. The version of the GNU compiler is different between these two sites - the XC40 uses GNU Fortran (GCC) 4.9.1 20140716 (Cray Inc.), whereas the VM uses GNU Fortran (Ubuntu 5.2.1-22ubuntu2) 5.2.1 20151010. The domain decomposition is different as well (4x4 on the XC40 vs. <nowiki>1x{{MPI_TASKS}}</nowiki> on the VM). [https://code.metoffice.gov.uk/trac/um/ticket/3127 #3127] has been opened to investigate this.
  
−
* '''AJH:''' ''Radaer can be run from GLOMAP-mode climatology files'' ([https://code.metoffice.gov.uk/trac/um/ticket/288 #288] )
  
   
  +
* '''Update from CSIRO:''' We have almost finalised the oceanic ozone dry deposition parameterisation work and at some point will need some guidance as to if and when this can be incorporated into the Trunk. See [[Minutes_of_the_code_management_group_meeting_2017-07-14#Highlights.2FTargets_from_CSIRO|point 2 from the last meeting]].

* '''Michael Hollaway:''' I currently have a test version of the code working that uses RADAER to pass the aerosol optical properties to FAST-JX. This runs at UM-UKCA 10.6.1. I am currently working on testing the code with different MODE setups and then will work on going through the required steps to get the code into the trunk at 10.9 (sci/tech review, code review, etc). All being well the updates should hopefully be ready for 10.9 (fingers crossed).

Redundant Code (LA for NS)

Redundant code

Code Proposed for Deletion

# Description Ticket Remarks Status Owner
1 Old emissions code (that which uses ancil files) #142 None Completed Mohit Dalvi
2 Old dry deposition scheme #2356 None PROPOSED Fiona O'Connor
3 ukca_volume_mode.F90 - quick method for calculating wet volume is not used since iwvolmethod is hard coded to equal 2. #2373 None Complete Alan J Hewitt
4 2D photolysis #2358 None Do not remove code Fiona O'Connor
5 ukca_strat_update.F90 - relax_ozone #1505 None PROPOSED Luke Abraham
6 Backward Euler Standard Tropospheric Chemistry #1507 None PROPOSED Fiona O'Connor
7 Wet oxidation of SO2 in GLOMAP None None PROPOSED Colin Johnson
  • Question: Should ALL schemes using the backward Euler solver be proposed for redundancy?

It was agreed that this should be a long-term aim, targeting offline-oxidants first. OpenMP work will proceed around the column-call to ASAD to speed this up and make it competitive.

MS has OpenMP code that has not been lodged, for Fast-JX and current ukca_chemistry_ctl routine (using lat/lon slice in the call to ASAD).

new action: FOC to arrange meeting between FOC, MR, MS, LA (& others who are interested) to sit down and decide a plan to move forward with OpenMP work, before new person starts.

new action: LA to update Redundant code tables with above information

Depreciated Code

# Description Ticket Remarks Status Owner
1 Deprecated UKCA netcdf attribute options #2513 'emission_type', string type attributes no longer recomeneded. Need some time for most new code to adopt these DEPRECATED Alistair Sellar

This code should not be removed for legacy reasons.

new action: MS to add bug in offline oxidants to bugfixes table.

Strategy for next UKCA Release Job (LA/MD)

MD has a free running TS2000 job, and is adding a nudging job. However, many users are requesting an AMIP job. While aerosol emissions are transient, chemical emissions are decadal means. It was noted that um:#3400 could be used as a potential AMIP base-job, but is still using climatological emissions. CMIP6 time-varying emissions still some weeks away.

new action: LA and MD to talk offline about releases.
