| 9 | !>\BRIEF Calculates the soil temperatures by solving the heat |
|---|
| 10 | !! diffusion equation within the soil. This module is only used with Choisnel hydrology. |
|---|
| 11 | !! |
|---|
| 12 | !!\n DESCRIPTION : General important informations about the numerical scheme and |
|---|
| 13 | !! the soil vertical discretization:\n |
|---|
| 14 | !! - the soil is divided into "ngrnd" (=7 by default) layers, reaching to as |
|---|
| 15 | !! deep as 5.5m down within the soil, with thiscknesses |
|---|
| 16 | !! following a geometric series of ration 2.\n |
|---|
| 17 | !! - "jg" is usually used as the index going from 1 to ngrnd to describe the |
|---|
| 18 | !! layers, from top (jg=1) to bottom (jg=ngrnd)\n |
|---|
| 19 | !! - the thermal numerical scheme is implicit finite differences.\n |
|---|
| 20 | !! -- When it is resolved in thermosoilc_profile at the present timestep t, the |
|---|
| 21 | !! dependancy from the previous timestep (t-1) is hidden in the |
|---|
| 22 | !! integration coefficients cgrnd and dgrnd, which are therefore |
|---|
| 23 | !! calculated at the very end of thermosoilc_main (call to |
|---|
| 24 | !! thermosoilc_coef) for use in the next timestep.\n |
|---|
| 25 | !! -- At timestep t, the system becomes :\n |
|---|
| 26 | !! |
|---|
| 27 | !! T(k+1)=cgrnd(k)+dgrnd(k)*T(k) \n |
|---|
| 28 | !! -- EQ1 -- \n |
|---|
| 29 | !! |
|---|
| 30 | !! (the bottom boundary condition has been used to obtained this equation).\n |
|---|
| 31 | !! To solve it, the uppermost soil temperature T(1) is required. |
|---|
| 32 | !! It is obtained from the surface temperature Ts, which is |
|---|
| 33 | !! considered a linear extrapolation of T(1) and T(2)\n |
|---|
| 34 | !! |
|---|
| 35 | !! Ts=(1-lambda)*T(1) -lambda*T(2) \n |
|---|
| 36 | !! -- EQ2--\n |
|---|
| 37 | !! |
|---|
| 38 | !! -- caveat 1 : Ts is called 'temp_soil_new' in this routine, |
|---|
| 39 | !! don' t act.\n |
|---|
| 40 | !! -- caveat 2 : actually, the surface temperature at time t Ts |
|---|
| 41 | !! depends on the soil temperature at time t through the |
|---|
| 42 | !! ground heat flux. This is again implicitly solved, with Ts(t) |
|---|
| 43 | !! expressed as :\n |
|---|
| 44 | !! |
|---|
| 45 | !! soilcap*(Ts(t)-Ts(t-1))/dt=soilflux+otherfluxes(Ts(t))\n |
|---|
| 46 | !! -- EQ3 --\n |
|---|
| 47 | !! |
|---|
| 48 | !! and the dependency from the previous timestep is hidden in |
|---|
| 49 | !! soilcap and soilflux (apparent surface heat capacity and heat |
|---|
| 50 | !! flux respectively). Soilcap and soilflux are therefore |
|---|
| 51 | !! calculated at the previsou timestep, at the very end of thermosoilc |
|---|
| 52 | !! (final call to thermosoilc_coef) and stored to be used at the next time step. |
|---|
| 53 | !! At timestep t, EQ3 is solved for Ts in enerbil, and Ts |
|---|
| 54 | !! is used in thermosoilc to get T(1) and solve EQ1.\n |
|---|
| 55 | !! |
|---|
| 56 | !! - lambda is the @tex $\mu$ @endtex of F. Hourdin' s PhD thesis, equation (A28); ie the |
|---|
| 57 | !! coefficient of the linear extrapolation of Ts (surface temperature) from T1 and T2 (ptn(jg=1) and ptn(jg=2)), so that:\n |
|---|
| 58 | !! Ts= (1+lambda)*T(1)-lambda*T(2) --EQ2-- \n |
|---|
| 59 | !! lambda = (zz_coeff(1))/((zz_coef(2)-zz_coef(1))) \n |
|---|
| 60 | !! |
|---|
| 61 | !! - cstgrnd is the attenuation depth of the diurnal temperature signal |
|---|
| 62 | !! (period : one_day) as a result of the heat conduction equation |
|---|
| 63 | !! with no coefficients : |
|---|
| 64 | !!\latexonly |
|---|
| 65 | !!\input{thermosoilc_var_init0.tex} |
|---|
| 66 | !!\endlatexonly |
|---|
| 67 | !! -- EQ4 --\n |
|---|
| 68 | !! This equation results from the change of variables : |
|---|
| 69 | !! z' =z*sqrt(Cp/K) where z' is the new depth (homogeneous |
|---|
| 70 | !! to sqrt(time) ), z the real depth (in m), Cp and K the soil heat |
|---|
| 71 | !! capacity and conductivity respectively.\n |
|---|
| 72 | !! |
|---|
| 73 | !! the attenuation depth of a diurnal thermal signal for EQ4 is therefore homogeneous to sqrt(time) and |
|---|
| 74 | !! equals : \n |
|---|
| 75 | !! cstgrnd = sqrt(oneday/Pi) |
|---|
| 76 | !! |
|---|
| 77 | !! - lskin is the attenuation depth of the diurnal temperature signal |
|---|
| 78 | !! (period : one_day) within the soil for the complete heat conduction equation |
|---|
| 79 | !! (ie : with coefficients) |
|---|
| 80 | !!\latexonly |
|---|
| 81 | !!\input{thermosoilc_var_init00.tex} |
|---|
| 82 | !!\endlatexonly |
|---|
| 83 | !! -- EQ5 -- \n |
|---|
| 84 | !! it can be retrieved from cstgrnd using the change of variable z' =z*sqrt(Cp/K):\n |
|---|
| 85 | !! lskin = sqrt(K/Cp)*cstgrnd = sqrt(K/Cp)*sqrt(oneday//Pi)\n |
|---|
| 86 | !! |
|---|
| 87 | !! In thermosoilc, the ratio lskin/cstgrnd is frequently used as the |
|---|
| 88 | !! multiplicative factor to go from |
|---|
| 89 | !!'adimensional' depths (like z' ) to real depths (z). z' is not really |
|---|
| 90 | !! adimensional but is reffered to like this in the code. |
|---|
| 91 | !! |
|---|
| 92 | !!--------------------------------------------------------------------------------------- |
|---|
| 93 | !! Modified by Dmitry Khvorostyanov and Gerhard Krinner 12-14/12/06 to account |
|---|
| 94 | !for permafrost |
|---|
| 95 | !! |
|---|
| 96 | !! - new subroutine 'thermosoilc_getdiff' that computes soil heat conductivity |
|---|
| 97 | !! and heat capacity with account for liquid and frozen phases |
|---|
| 98 | !! |
|---|
| 99 | !! - new subroutine 'thermosoilc_wlupdate' that computes long-term soil |
|---|
| 100 | !! humidity ensuring energy conservation when soil freezes |
|---|
| 101 | !! |
|---|
| 102 | !! - in 'thermosoilc_coef' and 'thermosoilc_var_init' the part computing the |
|---|
| 103 | !! soil capa and kappa has been rewritten in terms of the new routine 'thermosoilc_getdiff' |
|---|
| 104 | !! |
|---|
| 105 | !! - in the call to 'thermosoilc_var_init' the variable 'snow' is now passed |
|---|
| 106 | !! as an input argument in order to be able to use 'thermosoilc_getdiff' |
|---|
| 107 | !! |
|---|
| 108 | !! - 'thermosoilc_wlupdate' is called in 'thermosoilc_main', just after |
|---|
| 109 | !! 'thermosoilc_humlev', to update the long-term humidity |
|---|
| 110 | !! |
|---|
| 111 | !! - new module constants related to permafrost have been added |
|---|
| 112 | !! |
|---|
| 113 | !! - modifications related to the thermosoilc autonomy (optional output using |
|---|
| 114 | !! flio, no use of restart files, initial and boundary conditions specified in the call to |
|---|
| 115 | !! thermosoilc_main) |
|---|
| 116 | !!--------------------------------------------------------------------------------------- |
|---|
| 117 | !! Modified by Charlie Koven 2008-2010 and Tao Wang 2014 to: |
|---|
| 118 | !! |
|---|
| 119 | !! - added PFT dimension to soil thermal calculations |
|---|
| 120 | !! |
|---|
| 121 | !! - three-layer snow module from ISBA-ES |
|---|
| 122 | !! |
|---|
| 123 | !! - take into account soil carbon in the thermal properties of soil |
|---|
| 124 | !! Two possible modes, with separate organic layer on top of soil, or mixed mieral/organic soils |
|---|
| 125 | !! |
|---|
| 126 | !! - take into account exothermic heat of decomposition in heat budget of soil layers |
|---|
| 127 | !! |
|---|
| 128 | !! - output some diagnostic properties (soil moisture, etc) on soil temperature grid for use in |
|---|
| 129 | !! calculations within the permafrost soil carbon code. |
|---|
| 130 | !! |
|---|
| 131 | !!--------------------------------------------------------------------------------------- |
|---|
| 132 | !! |
|---|
| 133 | !! |
|---|
| 134 | !! RECENT CHANGE(S) : thermosoilc module is a copy of thermosoil before the vertical discretization was changed. |

| 646 | !! SUBROUTINE : thermosoilc_main |
|---|
| 647 | !! |
|---|
| 648 | !>\BRIEF Thermosoil_main computes the soil thermal properties and dynamics, ie solves |
|---|
| 649 | !! the heat diffusion equation within the soil. The soil temperature profile is |
|---|
| 650 | !! then interpolated onto the diagnostic axis. |
|---|
| 651 | !! |
|---|
| 652 | !! DESCRIPTION : The resolution of the soil heat diffusion equation |
|---|
| 653 | !! relies on a numerical finite-difference implicit scheme |
|---|
| 654 | !! fully described in the reference and in the header of the thermosoilc module. |
|---|
| 655 | !! - The dependency of the previous timestep hidden in the |
|---|
| 656 | !! integration coefficients cgrnd and dgrnd (EQ1), calculated in thermosoilc_coef, and |
|---|
| 657 | !! called at the end of the routine to prepare for the next timestep. |
|---|
| 658 | !! - The effective computation of the new soil temperatures is performed in thermosoilc_profile. |
|---|
| 659 | !! |
|---|
| 660 | !! - thermosoilc_coef calculates the coefficients for the numerical scheme for the very first iteration of thermosoilc; |
|---|
| 661 | !! after that, thermosoilc_coef is called only at the end of the module to calculate the coefficients for the next timestep. |
|---|
| 662 | !! - thermosoilc_profile solves the numerical scheme.\n |
|---|
| 663 | !! |
|---|
| 664 | !! - Flags : one unique flag : THERMOSOIL_TPRO (to be set to the desired initial soil in-depth temperature in K; by default 280K) |

|---|
| 1107 | !! 2. Defines the scaling coefficients for adimensional depths (lskin, cstgrnd, see explanation in the |
|---|
| 1108 | !! variables description of thermosoilc_main). \n |
|---|
| 1109 | !! 3. Calculates the vertical discretization of the soil (zz, zz_coef, dz2) and the constants used |
|---|
| 1110 | !! in the numerical scheme and which depend only on the discretization (dz1, lambda).\n |
|---|
| 1111 | !! 4. Initializes the soil thermal parameters (capacity, conductivity) based on initial soil moisture content.\n |
|---|
| 1112 | !! 5. Produces a first temperature diagnostic based on temperature initialization.\n |
|---|
| 1113 | !! |
|---|
| 1114 | !! The scheme comprizes ngrnd=7 layers by default. |
|---|
| 1115 | !! The layer' s boundaries depths (zz_coef) follow a geometric series of ratio zalph=2 and first term fz1.\n |
|---|
| 1116 | !! zz_coef(jg)=fz1.(1-zalph^jg)/(1-zalph) \n |
|---|
| 1117 | !! The layers' boudaries depths are first calculated 'adimensionally', ie with a |
|---|
| 1118 | !! discretization adapted to EQ5. This discretization is chosen for its ability at |
|---|
| 1119 | !! reproducing a thermal signal with periods ranging from days to centuries. (see |
|---|
| 1120 | !! Hourdin, 1992). Typically, fz1 is chosen as : fz1=0.3*cstgrnd (with cstgrnd the |
|---|
| 1121 | !! adimensional attenuation depth). \n |
|---|
| 1122 | !! The factor lskin/cstgrnd is then used to go from adimensional depths to |
|---|
| 1123 | !! depths in m.\n |
|---|
| 1124 | !! zz(real)=lskin/cstgrnd*zz(adimensional)\n |
|---|
| 1125 | !! Similarly, the depths of the numerical nodes are first calculated |
|---|
| 1126 | !! adimensionally, then the conversion factor is applied.\n |
|---|
| 1127 | !! the numerical nodes (zz) are not exactly the layers' centers : their depths are calculated as follows:\n |

|---|
| 1288 | !! DESCRIPTION : This routine computes : \n |
|---|
| 1289 | !! 1. the soil thermal properties. \n |
|---|
| 1290 | !! 2. the integration coefficients of the thermal numerical scheme, cgrnd and dgrnd, |
|---|
| 1291 | !! which depend on the vertical grid and on soil properties, and are used at the next |
|---|
| 1292 | !! timestep.\n |
|---|
| 1293 | !! 3. the soil apparent heat flux and surface heat capacity soilflux |
|---|
| 1294 | !! and soilcap, used by enerbil to compute the surface temperature at the next |
|---|
| 1295 | !! timestep.\n |
|---|
| 1296 | !! - The soil thermal properties depend on water content (shum_ngrnd_perma) and on the presence |
|---|
| 1297 | !! of snow : snow is integrated into the soil for the thermal calculations, ie if there |
|---|
| 1298 | !! is snow on the ground, the first thermal layer(s) consist in snow, depending on the |
|---|
| 1299 | !! snow-depth. If a layer consists out of snow and soil, wheighed soil properties are |
|---|
| 1300 | !! calculated\n |
|---|
| 1301 | !! - The coefficients cgrnd and dgrnd are the integration |
|---|
| 1302 | !! coefficients for the thermal scheme \n |
|---|
| 1303 | !! T(k+1)=cgrnd(k)+dgrnd(k)*T(k) \n |

|---|
| 1306 | !! their expression can be found in this document (eq A19 and A20) |

|---|
| 1309 | !! balance for Ts (EQ3); they correspond to $C_s$ and $F_s$ in F. |
