drift_correct: Instrument drift corrections

In ASRCsoft/atmoschem.datasets: ASRC Atmospheric Chemistry Data Processing

Instrument drift corrections

Description

Apply instrument drift corrections based on calibration check results.

Usage

drift_correct(t, v, z = NULL, s = NULL, config)

Arguments

t	Measurement times (POSIXct).
v	Measurement values.
z	Data frame of zero calibration checks. Should contain columns time, value, and corrected (logical, whether the instrument was adjusted).
s	Data frame of span calibration checks. Should contain columns time, value, and corrected (logical, whether the instrument was adjusted).
config	list of Configuration options from the measurement_types config table.

Details

Zero and span values are estimated using estimate_cals. If not provided, zeros and spans are assumed to be 0 and 1, respectively. The corrected values are calculated as (measurement - zero) / span.

Value

Drift-corrected measurements.
