In jkennel/hydrorecipes: Hydrogeology steps

step_baro_harmonic

Description

Estimate the static barometric efficiency using harmonic methods (Ratio, Acworth, Rau, Transfer)

Usage

step_baro_harmonic(
  .rec,
  time,
  water_level,
  barometric_pressure,
  earth_tide,
  frequency = c(1.9324, 2),
  cycle_size = 86400,
  starting_value = 0,
  inverse = FALSE,
  role = "augment",
  ...
)

Arguments

.rec	the R6 recipe object.
time	name of column that holds the time information
water_level	numeric vector of the dependent variable (ie:water level)
barometric_pressure	numeric vector of the independent variable (ie:barometric pressure)
earth_tide	variable unquoted Earth tide column name
frequency	numeric vector - the frequencies of the sin and cos curves
cycle_size	numeric - the period of the sin and cos curves
starting_value	numeric - the starting position of the sin and cos curves. This may be specified to have more control over the signal phase.
inverse	logical whether the barometric relationship is inverse
role	character - the name of the role
...	additional arguments

Value

double barometric efficiency using different methods
