Prepend Prewarm Climate to Your True Analysis Series

Takes your genuine, day 1 to day N climate vectors (temp, rain, etc.) and builds a single vector of length prewarm_years360 + analysis_days, where the first prewarm_years360 days are just repeats of the first 360 days of your real series, and the last analysis_days days are the real data you passed in.

Usage

extend_inputs_with_prewarm(
  param_inputs,
  start_date,
  end_date,
  prewarm_years,
  days_per_year = 360
)

Arguments

param_inputs

Named list of inputs, where time-varying elements include "cov_SMC", "SMC", "decay", "c_R_D", "temp". Each of those should be a numeric vector of length = raw_analysis_days.

start_date

Date at which your real series begins (e.g. "2018-01-01").

end_date

Date at which your real series ends (e.g. "2023-12-31").

prewarm_years

Integer number of 360-day years to prepend.

days_per_year

Number of days per model year (default: 360).

Value

A list like param_inputs but with each time-varying vector extended to length = prewarm_years*360 + floor(analysis_days/7)*7.
