 - 11 layers soil hydrology (ready)
+
+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)

+
+- Common soil vertical discretization between Hydrology and Thermics (ready)
+
+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
-General “scheme” to have flexible depth (to be implemented)
-Resp: Frederique, Agnes, Jan, Fuxing 
+
+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 Jan 2015)
+
 
 - New soil thermal properties (function of USDA soil texture classes) (ready)
-Tests made by Agnes & Fuxing ?
+
+Tests made by Agnes & Fuxing & Frederique ?
+
 
 - Soil freezing following I. Gouttevin’s Phd (ready)
-Current scheme conserve energy on annual basis (from freezing/thawing) 
-will be used as default.
+
+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 
+
 Need a working group (IG, GK, … ?)
 
+
+- New 3 layers snow module following Tao’s work 
+
+Resp: Catherine, Jan, Tao, Philippe C
+
+Trunc contain the latest version used in MICT (since Mai)
+
+Ongoing improvement to have a snow fraction and fully implicit coupling
+
+Action followed by a little group (FC, AD, JP, CO, JLD, PP, PC, TW, GK, JG, PM) with possible implementation by Fuxing and Jan
+
+
+
+- Adjusted albedos (en cours: objectif Juin 2015)
+
+Replace Bares Soil albedo by the “MODIS – Background Albedo” from JRC-TIP
+or from ECOCLIMAP-2
+
+Optimize the NIR and VIS 12 vegetation albedos using MODIS global albedo
+
+Ongoing action by PP and VB in Mai-June
+
+Resp. : Philippe P, Vladislav, Frederique
+
+
+- Nitrogen cycle (Autumn 2015)
+
+Resp: NV, DG, SP, BG, 
+
+Code ready, under debugging phase ; several persons involved (NV, SP, DG,…)
+
+Possible large impact on climate simulations: NEED TO LAUNCH first global 
+
+Test NO later than Mid October 2015
+
+Global forced and coupled tests to be done before end of 2015 
+
+
+- Permafrost and Yedoma deposit (to be decided, autumn 2015)
+
+Resp: PC, SP, ...
+
+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 substantial work!
+
+
+Crops
+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).
+Resp: Nicolas 1-2, Philippe C., Xuichen 
+
+Fires following SPITFIRE (to be decided) 
+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 !
+Resp: Patricia, Yue Chao, Philippe C.
+ 
+
+DGVM (late 2015)
+Ready for the High latitude PFTs ; Ongoing “check/calibration” for the tropics 
+Update of the Trunc before summer 2015 (for Paleo simul tests)
+Re-calibration “needed” when Nitrogen cycle will be included
+Implementation with ORC-CAN will require substantial tests/dev.
+Resp: Dan Zhu, Philippe C., Nicolas Viovy
