fit_function {neonSoilFlux}

Internal function that interpolates a soil measurement to different depths

Description

Definition function. Linearly interpolate a measurement across the different measurement depths

Usage

fit_function(
  input_depth,
  input_value,
  input_value_err,
  input_value_qf,
  interp_depth,
  measurement_special
)

Arguments

input_depth

Required. Vector of measurement depths.

input_value

Required. Vector of measured values (i.e. soil temperature and soil water) measured at depths input_depth

input_value_err

Required. Vector or reported measurement errors. Used to compute prediction error (via quadrature) when linear interpolation is used.

input_value_qf

Required. Vector of qf values from the smoothing 0 = no smoothing, 1 = mean value used (smoothing), 2 = NA value

interp_depth

Depths of the sensors required for interpolation

measurement_special

Flag if we want to just do linear interpolation for a given measurement

Value

A data frame of the depth and the measured column for the measurements and reported error
