This directory contains the results from model calibrations (directories Opt*) and cross validation experiments (directories Cross*). Iris Kriest, 14.1.2020 ************************************* * OPTIMISATIONS (directories Opt*) * ************************************* OptMIT28/ OptUHigh/ OptU20/ OptU17.5/ OptECCO/ Each directory contains: Annual mean tracers and fluxes: ------------------------------- A netCDF file of annual mean tracer concentrations and fluxes of year 3000 of individual number 1 of the last generation. Note that for ECCO the optimisation was stopped after 100 generations, when fitness varies only between 0.36562 and 0.36564. File naming within each directory is, e.g., - "UHighStar_avg.cdf" for average mean tracers of the optimal configuration in UHigh TMs. - "UHighStar_flux.cdf" for average mean fluxes of the optimal configuration in UHigh TMs. Units of annual mean tracer concentrations (files *_avg.cdf) are mmol/m3 for each tracer. Units of annual mean fluxes (files *_flux.cdf) are: photosynthesis : mmol P / m3 / ocean time step grazing : mmol P / m3 / ocean time step remineralisation : mmol P / m3 / ocean time step denitrification : mmol P / m3 / ocean time step nfixation : mmol N / m3 / ocean time step runoff : mmol P / m3 / ocean time step sedimentation : mmol P / m2 / ocean time step Note that: - Simulations with MIT28 and ECCO TMs have 720 ocean time steps per year -> multiply with 720 to obtain annual fluxes. - Simulations with UVic TMs have 1095 ocean time steps per year -> multiply with 1095 to obtain annual fluxes. - "sedimentation" is the flux or organic particles through the upper boundary of a grid box, i.e., the flux into a box. For box 1 (the uppermost box) it contains the burial flux at the sea floor. - "denitrification" is the amount of detritus and DOP decomposed anaerobically. To obtain the corresponding loss of nitrate multiply with 0.8*ro2ut , where ro2ut is parameter R_(-O2:P) (e.g., 151.1 for ECCOStar). Output of optimisation (optimisation trajectory): ------------------------------------------------- ASCII files containing output produced during the optimisation trajectory (10 individuals per each generation). nIter.txt - central file for optimiser setup; see directory "../Code/CMAES/README" fitness.tar.gz - model fitness (10 per generation) parameters.tar.gz - model parameters (10 per generation; see mode subroutine "mops_biogeochem_set_params.F" for parameter order) algVars.tar.gz - diagnostic output of CMAES (1 per generation) serial.tar.gz - diagnostic output of CMAES (1 per generation) logfile-omops-asciiparams.tar.gz - diagnostic output of model (10 per generation) ****************************************************** * CROSS-VALIDATION EXPERIMENTS (directories Cross*) * ****************************************************** Results from cross validation experiments, ordered according to circulation (TMs) applied. E.g., simulations carried out with ECCO TMs using different parameter sets are denoted as "CrossECCOTMs". CrossMIT28TMs/ - simulations with MIT28 TMs CrossUHighTMs/ - simulations with UHigh TMs CrossU20TMs/ - simulations with U20 TMs CrossU17.5TMs/ - simulations with U17.5 TMs CrossECCOTMs/ - simulations with ECCO TMs Each directory contains the annual mean tracers and fluxes of four simulations carried out with the parameter sets optimal for the four other simulations. E.g., for directory "CrossECCOTMs/": CrossECCOTMs/ECCO-MIT28Star_avg.cdf - annual mean tracers of simulation with ECCO TMs and parameters optimal for MIT28 CrossECCOTMs/ECCO-UHighStar_avg.cdf - annual mean tracers of simulation with ECCO TMs and parameters optimal for UHigh CrossECCOTMs/ECCO-U20Star_avg.cdf - annual mean tracers of simulation with ECCO TMs and parameters optimal for U20 CrossECCOTMs/ECCO-U17.5Star_avg.cdf - annual mean tracers of simulation with ECCO TMs and parameters optimal for U17.5 Units are the same as described for the optimal runs.
