Redundant code

This page is a starting point for discussion on code which is not being used and can be considered for removal. At this stage no decisions about any of these pieces of code have been made but in time it will become a place to record when things are planned to be deleted and then when they are deleted.

Table of code proposed for deletion

Status should be "proposed" until agreed for deletion at a code management group meeting. However, you are encouraged to open a ticket with the milestone set to 'HOPEFULLY' as soon as you propose something here. If the proposal is rejected the ticket can be closed. Code that exists but it no longer used can be set to depreciated.

NOTE: ALL GLOMAP CHANGES SHOULD BE DISCUSSED WITH LEEDS BEFORE PROCEEDING

#	Description	Ticket	Remarks	Status	Timeframe	Owner
1	Old emissions code (that which uses ancil files)	#142	None	Complete		Nick Savage
2	Old dry deposition scheme	#2356	None	PROPOSED	Medium-term	Nick Savage
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	ukca_strat_update.F90 - relax_ozone	#1505	None	PROPOSED	Medium-term	Luke Abraham
5	Backward Euler Standard Tropospheric Chemistry	#1507	None	PROPOSED	Medium-term	Fiona O'Connor
6	Wet oxidation of SO2 in GLOMAP	None	None	PROPOSED	Medium-term	Colin Johnson
7	Updraft velocity	#3668	Proposed in December 2017	PROPOSED	Medium-term	Alan J Hewitt
8	All backward Euler chemistry schemes	None	Note that this is only for the “hard-coded” BE schemes. Quite a lot of work would be involved, but good as a longer-term aim. Note that problems for AQUM would need to be addressed first.	PROPOSED	Long-term	Luke Abraham
9	Deprecated UKCA netcdf attribute options	#2513	'emission_type', string type attributes no longer recommeneded. Need some time for most new code to adopt these. Still used in AQUM files.	DEPRECATED	Long-term	Nick Savage
