coupling frequency units

Reported by: rupert Owned by: gerry
Priority: minor Milestone: V1.2 Questionnaire release
Component: WP6 - CMIP5 Questionnaire Version:
Keywords: Cc:
Requirement: http://metaforclimate.eu/Work-Package-2/Developing-the-CIM/Project-Requirements-summary.htm

Description

The coupling frequency allows different units. This is good. However, the timestep of a component (if provided) is fixed to be in seconds in the mindmaps. The issue is how we convert the values if needed, seeing as different models can use different calendars. We might want to do this to know how many timesteps a component makes between coupling. Should we ask for calendar type for the components/model as well, or am I going over the top here?

How many times does a calendar type actually impact on either timestepping or coupling? The only time this is likely to be a problem is with ESM into deep time, where seconds for timestepping might not be a good solution anyway? Is the problem in the mindmaps?

The component timestep information is not being explicitly provided in the questionnaire (via the mindmaps). Rather it is a general component property that may or may not exist. Therefore the CIM element that captures the timestep of a component will not be populated. This means that it will not be possible to compare timestepping and coupling rates. Closing this ticket as won't fix.

Reopen, as this is something that still needs thinking about, even if we don't put it in the current release of the questionnaire.
