A method of calibrating a measurement device includes: compiling historical calibration data for the measurement device, the historical calibration data including values corresponding to outputs of the measurement device over a first operating duration in environmental conditions associated with an operating environment; projecting the historical calibration data over a subsequent operating duration to generate predictive calibration data; disposing the measurement device in the operating environment and generating measurement signals during the first operating duration and the subsequent operating duration; and generating measurement values from measurement signals generated during the subsequent operating duration based on the predictive calibration data.
