9 | !>\BRIEF Calculates the soil temperatures by solving the heat |
---|
10 | !! diffusion equation within the soil. This module is only used with CWRR hydrology. |
---|
11 | !! |
---|
12 | !!\n DESCRIPTION : General important informations about the numerical scheme and |
---|
13 | !! the soil vertical discretization:\n |
---|
14 | !! - the soil is zmaxt deep (by default 10m) and divided into "ngrnd" layers. |
---|
15 | !! From 0-zmaxh(default 2m), the discretization is the same as for hydrology. |
---|
16 | !! From zmaxh(2m) and below, the depth increase linearly (by default) or geometrically. \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 thermosoil_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 thermosoil_main (call to |
---|
24 | !! thermosoil_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=soilflx+otherfluxes(Ts(t))\n |
---|
46 | !! -- EQ3 --\n |
---|
47 | !! |
---|
48 | !! and the dependency from the previous timestep is hidden in |
---|
49 | !! soilcap and soilflx (apparent surface heat capacity and heat |
---|
50 | !! flux respectively). Soilcap and soilflx are therefore |
---|
51 | !! calculated at the previous timestep, at the very end of thermosoil |
---|
52 | !! (final call to thermosoil_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 thermosoil 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 = (zlt(1))/((zlt(2)-zlt(1))) \n |
---|
60 | !! |
---|
61 | !! RECENT CHANGE(S) : - Change soil thermal properties to consider also soil texture, rev 2922. |
---|
62 | !! - Change vertical discretization, rev 2917. Note: In the revised thermosoil, |
---|
63 | !! cstgrnd and lskin are not needed any more. The depth znt, zlt and dlt |
---|
64 | !! are computed in vertical_soil and are in meter |

706 | !! the heat diffusion equation within the soil. |
---|
707 | !! |
---|
708 | !! DESCRIPTION : The resolution of the soil heat diffusion equation |
---|
709 | !! relies on a numerical finite-difference implicit scheme |
---|
710 | !! fully described in the reference and in the header of the thermosoil module. |
---|
711 | !! - The dependency of the previous timestep hidden in the |
---|
712 | !! integration coefficients cgrnd and dgrnd (EQ1), calculated in thermosoil_coef, and |
---|
713 | !! called at the end of the routine to prepare for the next timestep. |
---|
714 | !! - The effective computation of the new soil temperatures is performed in thermosoil_profile. |
---|
715 | !! |
---|
716 | !! - thermosoil_coef calculates the coefficients for the numerical scheme for the very first iteration of thermosoil; |
---|
717 | !! after that, thermosoil_coef is called only at the end of the module to calculate the coefficients for the next timestep. |
---|
718 | !! - thermosoil_profile solves the numerical scheme.\n |
---|
719 | !! |
---|
720 | !! - Flags : one unique flag : THERMOSOIL_TPRO (to be set to the desired initial soil in-depth temperature in K; by default 280K) |
---|
721 | !! |
---|
722 | !! RECENT CHANGE(S) : Change vertical discretization (consistent with hydrology layers) and soil thermal properties (taking into account soil texture effects). |
---|

---|
724 | !! MAIN OUTPUT VARIABLE(S): vertically discretized soil temperatures ptn, soil |
