fmi_spectra: Create reference model spectra catalogue

In coffeemuggler/eseis: Environmental Seismology Toolbox

Create reference model spectra catalogue

Description

In order to run the fluvial model inversion (FMI) routine, a look-up table with reference spectra needs to be created (based on predefined model parameters). This function does this job.

Usage

fmi_spectra(parameters, n_cores = 1)

Arguments

parameters	List containing lists with model parameters for which the spectra shall be calculated.
n_cores	Numeric value, number of CPU cores to use. Disabled by setting to 1. Default is 1.

Value

List object containing the calculated reference spectra and the corresponding input parameters. Note that the spectra are given in dB for a seamless comparison with the empirical PSD data, while the original output of the models are in linear scale.

Examples

## create 2 example reference parameter sets
ref_pars <- fmi_parameters(n = 2,
                           h_w = c(0.02, 2.00),
                           q_s = c(0.001, 50.000) / 2650,
                           d_s = 0.01,
                           s_s = 1.35,
                           r_s = 2650,
                           w_w = 6,
                           a_w = 0.0075,
                           f_min = 5,
                           f_max = 80,
                           r_0 = 6,
                           f_0 = 1,
                           q_0 = 10,
                           v_0 = 350,
                           p_0 = 0.55,
                           e_0 = 0.09,
                           n_0_a = 0.6,
                           n_0_b = 0.8,
                           res = 100)

## create corresponding reference spectra
ref_spectra <- fmi_spectra(parameters = ref_pars)
