`fdk_format_drivers` works for rsofun pmodel, but not rsofun BiomeE model.

[fabern]

fdk_format_drivers() aims to generate a driver object for the rsofun package. This includes:

• defining the time series forcing based on the FDK data
• defining other constant parameters to run the rsofun model
  • for pmodel
  • for BiomeE

These additional parameters have previously been defined in the fdk_format_drivers() for the pmodel part of the rsofun package (params_siml), but not yet for the BiomeE part (requiring site_info, params_siml, params_tile, params_species, params_soil, init_cohort). Below a list of the quantitites that need to be defined.

• To make it work with BiomE-model in a similar way, the following additional parameters would need to be defined, too:

  • site_info (needed, but passed as argument to fdk_format_drivers):
    • lon, lat, evl, year_start, year_end, classid, c4, whc, koeppen_code, igbp_land_use, plant_functional_type, date_start, and date_end
  • params_siml containing:
    • spinup, spinupyears, recycle, firstyeartrend, nyeartrend, steps_per_day, do_U_shaped_mortality, update_annualLAImax, do_closedN_run, method_photosynth, method_mortality
  • params_tile containing:
    • soiltype, FLDCAP, WILTPT, K1, K2, K_nitrogen, MLmixRatio, etaN, LMAmin, fsc_fine, fsc_wood, GR_factor, l_fract, retransN, f_initialBSW, f_N_add, tf_base, par_mort, par_mort_under
  • params_species containing:
    • lifeform, phenotype, pt, alpha_FR, rho_FR, root_r, root_zeta, Kw_root, leaf_size, Vmax, Vannual, wet_leaf_dreg, m_cond, alpha_phot, gamma_L, gamma_LN, gamma_SW, gamma_FR, tc_crit, tc_crit_on, gdd_crit, betaON, betaOFF, alphaHT, thetaHT, alphaCA, thetaCA, alphaBM, thetaBM, seedlingsize, maturalage, v_seed, mortrate_d_c, mortrate_d_u, LMA, leafLS, LNbase, CNleafsupport, rho_wood, taperfactor, lAImax, tauNSC, fNSNmax, phiCSA, CNleaf0, CNsw0, CNwood0, CNroot0, CNseed0, Nfixrate0, NfixCost0, internal_gap_frac, kphio, phiRL, LAI_light
  • params_soil containing:
    • type, GMD, GSD, vwc_sat, chb, psi_sat_ref, k_sat_ref, alphaSoil, heat_capacity_dry
  • init_cohort containing:
    • init_n_cohorts, init_cohort_species, init_cohort_nindivs, init_cohort_bl, init_cohort_br, init_cohort_bsw, init_cohort_bHW, init_cohort_seedC, init_cohort_nsc
  • init_soil containing:
    • init_fast_soil_C, init_slow_soil_C, init_Nmineral, N_input

• Note that defining these default parameters creates a version dependency between FDK and rsofun. It might be more robust to define default parameters for rsofun in the rsofun package (e.g. creating a rsofun::biomee_default_params = list(params_sim = ..., params_species = ...)) and using them from within the FluxDataKit::fdk_format_drivers function.

Is this still unresolved by recent modifications to homogenize forcings? @fabern

[fabern]

Yes this is still an open issue. I modified the original post to clarify that it is about defining default parametrization of BiomeE to be able to create a runnable driver.
