Abstract
A method for baseline calibration of methane sensor includes receiving data characterizing methane detection by a sensor and sensor measurement parameters. The received data characterizing methane detection includes a plurality of methane measurements and detection times associated with the plurality of methane measurements. The method also includes determining a first plurality of calibrated methane measurements by at least calibrating the plurality of methane measurement based on the sensor measurement parameters and one or more of a humidity and a temperature associated with the sensor. The method further includes calculating an offset parameter based on a difference between a global baseline reference and one of a previous baseline value and a measurement baseline value associated with the first plurality of calibrated methane measurements. The method also includes providing a second plurality of calibrated methane measurements by at least subtracting the offset parameter from the first plurality of calibrated methane measurements.
