Agenda of the developments

Description of the development Agenda for 2015 : Agenda development of CMIP6

The agenda propose a set of Actions by little groups to be done before 2015 for merging into the TRUNC all developments that are needed to perform CMIP6 v1 (and also the Very low resolution case focussing on Chemistry)

Note that we agreed that CMIP6 will be done only with the TRUNC so that we need to merge all developments into the TRUNC

For each "merging Dev tasks" few informations are also provided in the attached pdf

Any remarks, progresses about each task should be reported in the section below

Working Groups

Developement of the physical component for CMIP6-V1

See specific page of the Agenda and progresses under Physic for CMIP6?

Developement of the Biogeochemical component for CMIP6-V1

See specific page of the Agenda and progresses under Biogeochemistry for CMIP6

Improvement of Land-cover management (LCC) for CMIP6-V1

See specific page of the Agenda and progresses under LandCoverChanges for CMIP6

MERGES: progress and comments

To be updated when questions appear or when developments are improving

• 11 layers soil hydrology (ready)

Improvement over summer with “some work on W stress functions” No large conceptual changes Common soil vertical discretization between Hydrology and Thermics (ready) Soil thermics goes up to 10 meter Hydrology stops most likely at 2 m; Test by Fuxing to choose for CM6 General “scheme” to have flexible depth (to be implemented) Resp: Frederique, Agnes, Jan, Fuxing

• New soil thermal properties (function of USDA soil texture classes) (ready)

Tests made by Agnes & Fuxing ?

• Soil freezing following I. Gouttevin’s Phd (ready)

Current scheme conserve energy on annual basis (from freezing/thawing) will be used as default. Revision is planned for “instantaneous” conservation (late 2015) Need a working group (IG, GK, … ?)
