     55 
     56Hydrology stops most likely at 2 m; Test by Fuxing to choose for CM6 are ongoing 
     57 
     58a general “scheme” to have flexible depth need to be implemented (following a group discussion in Jan 2015) 
     59 
    4960 
    5061- New soil thermal properties (function of USDA soil texture classes) (ready) 
    51 Tests made by Agnes & Fuxing ?

     64 
    5265 
    5366- Soil freezing following I. Gouttevin’s Phd (ready) 
    54 Current scheme conserve energy on annual basis (from freezing/thawing)  
    55 will be used as default. 
     67 
     68Current scheme conserve energy on annual basis (from freezing/thawing) and will be used as default. 
     69 
    5670Revision is planned for “instantaneous” conservation (late 2015) 
     71 
     72Use of the "Diag_level" should be droped after the  
     73 
    5774Need a working group (IG, GK, … ?) 
    5875 
     76 
     77- New 3 layers snow module following Tao’s work  
     78 
     79Resp: Catherine, Jan, Tao, Philippe C 
     80 
     81Trunc contain the latest version used in MICT (since Mai) 
     82 
     83Ongoing improvement to have a snow fraction and fully implicit coupling 
     84 
     85Action followed by a little group (FC, AD, JP, CO, JLD, PP, PC, TW, GK, JG, PM) with possible implementation by Fuxing and Jan 
     86 
     87 
     88 
     89- Adjusted albedos (en cours: objectif Juin 2015) 
     90 
     91Replace Bares Soil albedo by the “MODIS – Background Albedo” from JRC-TIP 
     92or from ECOCLIMAP-2 
     93 
     94Optimize the NIR and VIS 12 vegetation albedos using MODIS global albedo 
     95 
     96Ongoing action by PP and VB in Mai-June 
     97 
     98Resp. : Philippe P, Vladislav, Frederique 
     99

     101- Nitrogen cycle (Autumn 2015) 
     102 
     103Resp: NV, DG, SP, BG,  
     104 
     105Code ready, under debugging phase ; several persons involved (NV, SP, DG,…) 
     106 
     107Possible large impact on climate simulations: NEED TO LAUNCH first global  
     108 
     109Test NO later than Mid October 2015 
     110 
     111Global forced and coupled tests to be done before end of 2015  
     112 
     113 
     114- Permafrost and Yedoma deposit (to be decided, autumn 2015) 
     115 
     116Resp: PC, SP, ... 
     117 
     118Permafrost module currently implemented in MICT version 
     119 
     120Main impact is a source of CO2 to the Atm.; small impact on soil thermal properties 
     121 
     122Yedoma (deep permafrost): impact through CO2 emissions 
     123 
     124“coupling” with the new E/W soil discretization need to be done;  
     125 
     126Extrapolation of the W content below soil W depth to be chosen 
     127 
     128Need substantial work! 
     129 
     130 
     131Crops 
     132Addition of a distinction between winter and spring C3 crops (phenology) 
     133Small change to be added autumn 2015 
     134POSSIBLE inclusion of ORC-CROP modules (to be discuss Autumn 2015). 
     135Resp: Nicolas 1-2, Philippe C., Xuichen  
     136 
     137Fires following SPITFIRE (to be decided)  
     138Coupling with Trunc to be done in September 2015 (small effort) 
     139Forcing for “human-induced” fires need to be prepared 
     140Modification of the albedo following fires under “implementation” 
     141Implementation with ORC-CAN: need to select “burned” trees ! 
     142Resp: Patricia, Yue Chao, Philippe C. 
     143  
     144 
     145DGVM (late 2015) 
     146Ready for the High latitude PFTs ; Ongoing “check/calibration” for the tropics  
     147Update of the Trunc before summer 2015 (for Paleo simul tests) 
     148Re-calibration “needed” when Nitrogen cycle will be included 
     149Implementation with ORC-CAN will require substantial tests/dev.
