calibrate_ambient_carbon_linreg

Usage

calibrate_ambient_carbon_linreg(
  amb_data_list,
  caldf,
  site,
  filter_data = TRUE,
  force_to_end = TRUE,
  force_to_beginning = TRUE,
  gap_fill_parameters = FALSE,
  r2_thres = 0.9
)

Arguments

amb_data_list: List containing an ambient d13C dataset. Will include all variables in 000_0x0_xxm. (character)
caldf: Calibration data frame containing gain and offset values for 12C and 13C isotopologues.
site: Four-letter NEON code corresponding to site being processed.
filter_data: Apply median absolute deviation filter from Brock 86 to remove impulse spikes? Inherited from calibrate_ambient_carbon_linreg
force_to_end: In given month, calibrate ambient data later than last calibration, using the last calibration? (default true)
force_to_beginning: In given month, calibrate ambient data before than first calibration, using the first calibration? (default true)
gap_fill_parameters: Should function attempt to 'gap-fill' across a bad calibration by carrying the last good calibration forward? Implementation is fairly primitive currently, as it only carries the last known good calibration that's available forward rather than interpolating, etc. Default FALSE.
r2_thres: Minimum r2 value for calibration to be considered "good" and applied to ambient data.

Value

Nothing to environment; returns calibrated ambient observations to the function orchestrating calibration (calibrate_carbon). This function is not designed to be called on its own, and is not exported to the namespace.

Function called by calibrate_ambient_carbon_linreg to apply gain and offset parameters to the ambient datasets (000_0x0_09m and 000_0x0_30m). This function should generally not be used independently, but should be used with calibrate_ambient_carbon_linreg.
