Current Bugs
List of bugs that need to be fixed. They are order by priority from the top to the bottom.
Spitfire
There are regative values at fuel_XXhr variables
Suppously, solved at r3021 and r3022. It seems it is not like this.
Multiple floating point exceptions at reat_of_spread
There is a floating overflow exception at exp(XXXX) from lpj_spitfire.f90 -> rate_of_spread
! reaction intensity a(:)=8.9033*(sigma(:)**(-0.7913)) WHERE (a(:).le.0.00001 .OR. bet(:).le.0.00001) dummy(:)=0.0 ELSEWHERE dummy(:)=exp(a(:)*(1.0-bet(:))) ENDWHERE
Proposed solution: set sigma values to 10000. FAILED
!calculate mass weighted surface-area-to-volume ratio by fuel types. WHERE (dead_fuel(:).gt.min_stomate) sigma(:)=(fuel_1hr_total(:) * sigma_1hr + & fuel_10hr_total(:) * sigma_10hr + & fuel_100hr_total(:) * sigma_100hr) / dead_fuel(:) ELSEWHERE sigma(:)=0.00001 -> 10000 ENDWHERE
Proposed solution: check sigma instead of a. OK (Accepted by Chao and Fabienne)
! reaction intensity a(:)=8.9033*(sigma(:)**(-0.7913)) WHERE (sigma(:).le.0.00001 .OR. bet(:).le.0.00001) dummy(:)=0.0 ELSEWHERE dummy(:)=exp(a(:)*(1.0-bet(:))) ENDWHERE
PFT maps and Analytic spinup with DGVM
There are no trees with DGVM (without spitfire)
You have a list in pft_parameters:
!! 5.1 Read the name of the PFTs given by the user ! !Config Key = PFT_NAME !Config Desc = Name of a PFT !Config if = OK_SECHIBA or OK_STOMATE !Config Def = bare ground, tropical broad-leaved evergreen, tropical broad-leaved raingreen, !Config temperate needleleaf evergreen, temperate broad-leaved evergreen temperate broad-leaved summergreen, !Config boreal needleleaf evergreen, boreal broad-leaved summergreen, boreal needleleaf summergreen, !Config C3 grass, C4 grass, C3 agriculture, C4 agriculture !Config Help = the user can name the new PFTs he/she introducing for new species !Config Units = [-] CALL getin_p('PFT_NAME',pft_name)
I'm looking at DGVM without SPITFIRE. In dynamic mode, we have first crops but natural PFTs appear later: grasses and after a few years trees. At least that's how it behaves with the TRUNK version.
VSD merge
How to deal with already designed MICT soil layers ?
Hi Shushi,
I made a mystake last Monday because the new vertical discretization had not yet been integrated in Albert's personal branch. Albert is now working on it and we have a few questions.
In Albert's branch, we have two possible different sets of values for soil_capa and soil_cond based on the keyword SOIL_LAYERS_DISCRE_METHOD (see constantes_soil.f90 and get_discretization_constants in thermosoil.f90).
This gives access to two different vertical discretization shemes (see thermosoil_levels). I copied all this relevant code below.
- Do we agree that we completely let down these two discretization schemes to get the new one (see vertical_soil_init)?
- I have the impression that soil_capa and soil_cond may intervene elsewhere, do we still keep the two different sets of values?
