	Many of us are using modelling more or less extensively as a part of our thesis and even if one wouldn’t be using any model, it would be very beneficial to have some knowledge about model set-up just to be able to read the literature and analyse the data. Also it is relatively easy to get access to different model codes in general and even set up an experiment. However, it might be often be that the user doesn't understand all (or maybe any of) the issues related to the set-up and in the worst case one might try to interpret some model artefacts as meaningful results. We hope this course could give some insight in these issues.

	~~==Brainstorming agenda and notes==~~
	~~#Opening up the session '''notes with bold'''~~
	~~#When should this class be held? (10 min)~~
	~~#*The suggestion from students was November-December (say before AGU fall meeting), is that too optimistic?~~
	~~#*'''It was decided that January would be better'''~~
	~~#**Anything outside the 13-15th would work. Best would be either 6th-10th or 19-23th of January 2014~~
	~~#Topics of the class and time plan (20 min)~~
	~~#*Should something be added or taken away?~~
	~~#*Does the time plan seem reasonable? Is the order of things reasonable, is there too little time?~~
	~~#*'''See the learning outcomes'''~~
	~~#Lectures/lecturers (40 min)~~
	#*We would suggest to have two sessions each day. Each sessions would have approximately 2 lectures and assigned organisers. They could then keep the lectures on their own or invite someone else to speak.
	~~#*Sessions could be also workshop type: 1 lecture after which discussion about the topic based on the lecture and some previously assigned literature.~~
	~~#*'''See the learning outcomes'''~~
	~~#**The workshop type lecturing was supported~~
	~~#*Assigning organisers/speakers~~
	~~#Sensitivity studies (20 min)~~
	~~#*Should be relatively easy to set up and run, but at the same time interesting enough~~
	~~#*Suggestions include: different grids, time stepping (probably not possible), slab ocean vs full ocean, land-use etc.~~
	~~#*Is this feasible?~~
	~~#*'''It was decided that although most interesting for some, it should not be part of this class'''~~
	~~#**There is a ResClim downscaling class planned for next summer (more hands-on)~~
	~~#Wrapping up (15 min)~~
	~~#*Does everyone know what to do to make this happen?~~
	~~#*Suggestions or other ideas we should still consider?~~
	~~#*'''Named people will contact outside lecturers'''~~
	~~#*'''Students will have a short meeting together to see if the plan is suitable and to discuss the structure a bit'''~~
	~~#Next meeting (5 min)~~
	~~#*Probably one short meeting required with everyone involved before the class starts~~
