mesmer.create_emulations.make_realisations(preds_lt, params_lt, params_lv, params_gv_T, time, n_realisations, seeds, land_fractions)#

Make climate realisations based on pre-calculated MESMER parameters

Parameters:

  • preds_lt (dict) – nested dictionary of predictors for local trends with keys

    • [pred][scen] (1d/ 2d arrays (time)/(run, time) of predictor for specific scenario)

  • params_lt (dict) – dictionary with the trained local trend parameters

    • [“targs”] (emulated variables, str)

    • [“esm”] (Earth System Model, str)

    • [“method”] (applied method, str)

    • [“method_each_gp_sep”] (states if method is applied to each grid point separately, bool)

    • [“preds”] (predictors, list of strs)

    • [“scenarios”] (emission scenarios used for training, list of strs)

    • [xx] (additional params depending on method employed)

    • [“full_model_contains_lv”] (whether the full model contains part of the local variability module, bool)

  • params_lv (dict) – dictionary with the trained local variability parameters

    • [“targ”] (variable which is emulated, str)

    • [“esm”] (Earth System Model, str)

    • [“method”] (applied method, str)

    • [“preds”] (predictors, list of strs)

    • [“scenarios”] (scenarios which are used for training, list of strs)

    • [xx] (additional keys depend on employed method)

  • params_gv_T (dict) –

    • [“targ”] (variable which is emulated, str)

    • [“esm”] (Earth System Model, str)

    • [“method”] (applied method, str)

    • [“preds”] (predictors, list of strs)

    • [“scenarios”] (scenarios which are used for training, list of strs)

    • [xx] (additional keys depend on employed method and are listed in train_gv_T_method() function)

  • time (dict) –

    • [“scenario”] timepoints (1D np.ndarray) used for training of the scenario (note that hist and scenario e.g. ssp126 are kept separate)

  • n_realisations (int) – Number of realisations to draw

  • seeds (dict) –

    • [“esm”] (dict):
      [“scenario”] (dict):

      [“gv”] (seed for global variability) [“lv”] (seed for local variability)

  • land_fractions (xr.DataArray) – Land fractions of each cell. Used to convert the MESMER outputs back onto grids.
