Patent ID: 8433525

Claim:
A gas analysis data handling device comprising: a processor; a communication interface to receive data from one or more measuring devices; and a memory store for storing data received by the communication interface, the processor configured to: receive a plurality data, the plurality of data including: a plurality of gas density measurement data for a target gas; a plurality of wind speed measurement data indicative of speed of movement of the target gas; a plurality of water vapor density measurement data indicative of water content in the target gas; a plurality of temperature measurement data; and a barometric pressure; determine a raw flux of the target gas based on the plurality of gas density data for the target gas and the plurality of wind speed measurement data; determine a water dilution effect based on the plurality of water vapor density measurement data; determine a thermal expansion value based on the plurality of temperature measurement data; determine an equivalent pressure based on the barometric pressure, the plurality of temperature measurement data, the plurality of water vapor density measurement data, and a water vapor broadening coefficient; and compute the gas flux of the target gas based on the raw flux, the water dilution effect, and the thermal expansion value, wherein at least one of the raw flux, the water dilution effect, or the thermal expansion value is adjusted by a multiplication factor determined based on an instrument response function of the instrument used to obtain the gas density measurement data, the response function relating actual gas density and measured gas density of the target gas as a function of temperature and equivalent pressure.
