In Burke-Lauenroth-Lab/rSFSW2: Simulation Framework for SOILWAT2

Description

Downscale with the 'delta approach'

Usage

downscale.delta(
  obs.hist.daily,
  obs.hist.monthly,
  scen.hist.monthly,
  scen.fut.monthly,
  itime,
  years = NULL,
  sim_time = NULL,
  opt_DS = list(ppt_type = "detailed", sigmaN = 6, PPTratioCutoff = 10),
  dailyPPTceiling,
  do_checks = TRUE,
  ...
)

Arguments

obs.hist.daily	A list. Each element corresponds to one year of simstartyr:endyr is an object of rSOILWAT2::swWeatherData.
obs.hist.monthly	A numeric matrix. Monthly time-series of observed weather calculated from obs.hist.daily for the years simstartyr:endyr.
scen.hist.monthly	A numeric matrix. Monthly time-series of scenario weather during the historic time period DScur_startyr:DScur_endyr
scen.fut.monthly	A numeric matrix. Monthly time-series of scenario weather during the projected time period DSfut_startyr:DSfut_endyr
opt_DS	A named list.
do_checks	A logical value. If TRUE perform several sanity checks on the data.
