To be updated when questions appear or when developments are improving
- 11 layers soil hydrology (ready, in the trunk)
Main Resp: Jan, Agnes,
Improvement over summer with “some work on W stress functions”
No large conceptual changes
- Common soil vertical discretization between Hydrology and Thermics (ready, not yet commited in the trunk)
Main Resp: Frederique, Agnes, Jan
Soil thermics goes up to 10 meter
Hydrology stops most likely at 2 m; Test by Fuxing to choose for CM6 are ongoing
a general “scheme” to have flexible depth need to be implemented (following a group discussion in January 2015)
- New soil thermal properties (function of USDA soil texture classes) (ready, in the trunk)
Main Resp: Agnes, Frederique
Tests made by Agnes & Fuxing & Frederique ?
- Soil freezing following I. Gouttevin’s Phd (ready, in the trunk but improvement to be done)
Current scheme conserve energy on annual basis (from freezing/thawing) and will be used as default.
Revision is planned for “instantaneous” conservation (late 2015)
Use of the "Diag_level" should be droped after the common soil vertical discretization
Need a working group (IG, GK, …) ?
- New 3 layers snow module (in the trunk, improvement on going)
following Tao Wang's work.
Main Resp: Catherine, Tao, Philippe C, Jan
Trunc contain the latest version used in MICT (since Mai)
Ongoing improvement to have a snow fraction and fully implicit coupling
Actions will be followed by a little group (FC, AD, JP, CO, JLD, PP, PC, TW, GK, JG, PM) with possible implementation by Fuxing and Jan
- Adjustment of the albedos (on going: objectif Juin 2015)
Replace Bares Soil albedo by the “MODIS – Background Albedo” from JRC-TIPor from ECOCLIMAP-2
Optimize the NIR and VIS 12 vegetation albedos using MODIS global albedo
Ongoing action by PP and VB in Mai-June
Main Resp. : Philippe P, Vladislav, Frederique
- Nitrogen cycle (Autumn 2015)
Main Resp: Nicolas, Bertrand, Sushi, Daniel, Philippe C
Code ready, under debugging phase
Possible large impact on climate simulations: NEED TO LAUNCH first global tests NO later than Mid October 2015
Global forced and coupled tests to be done and analysed before end of 2015
- Permafrost and Yedoma deposit (to be decided, spring 2016)
Main Resp: Philippe C., Dan, Shushi
Permafrost module currently implemented in MICT version
Main impact is a source of CO2 to the Atm.; small impact on soil thermal properties
Yedoma (deep permafrost): impact through CO2 emissions
“coupling” with the new E/W soil discretization need to be done
Extrapolation of the W content below soil W depth to be chosen
Need some work for the integration with the selected upper soil T/W common discretization
- Crops
Main Resp: Nicolas 1-2, Philippe C., Xuichen
Addition of a distinction between winter and spring C3 crops (phenology)
Small change to be added autumn 2015
POSSIBLE inclusion of ORC-CROP modules (to be discuss Autumn 2015).
- Fires following SPITFIRE (to be added in the trunk in beginning of autumn)
Main Resp: Patricia, Yue Chao, Philippe C.
Coupling with Trunc to be done in September 2015 (small effort)
Forcing for “human-induced” fires need to be prepared
Modification of the albedo following fires under “implementation”
Implementation with ORC-CAN: need to select “burned” trees !
- DGVM (ready, in the trunk, some calibration needed)
Main Resp: Philippe C., Nicolas Viovy, Dan Zhu
Ready for the High latitude PFTs ; Ongoing “check/calibration” for the tropics
Update of the Trunc already done (In May 2015 for Paleo simul tests)
Re-calibration “needed” when Nitrogen cycle will be included
Implementation with ORC-CAN will require substantial tests/dev.
- SPECIFIC MERGES FOR CMIP6-V2
CMIP6-V2 will be based on the NEW FOREST REPRESENTATION (ORC-CAN) including:
- Forest management
- Two streams radiation transfer scheme
- Canopy structure
- Age classes (LCC/LM)
- Hydraulic stress for trees
- Crop management
- Dynamic phosphorous cycle ?
- New plant functional types (Mosses/lichens & Shrub)
- New soil carbon module with « Priming » and DOC, POC, Vertical discretization,….
