Compute sea_state parameter from wave directional spectrum

Usage

compute_sea_state_2d_spectrum(spec, ...)

Arguments

spec: 2D spectrum data, e.g. from get_2Dspectrum
...: currently unused

Value

a tibble with the sea-state parameters computed from the time series of 2D spectrum

Examples

rscd_params <- get_parameters(
  node = "134865",
  start = "1994-01-01",
  end = "1994-01-31 23:00:00",
  parameters = c("hs", "tp", "cge", "t01", "dp", "dir")
)
spec <- resourcecodedata::rscd_2d_spectra
param_calc <- compute_sea_state_2d_spectrum(spec)
oldpar <- par(mfcol = c(2, 2))
