Patent ID: 7953558

Claim:
A non-transitory computer-readable storage medium having stored thereon computer program code for determining gas flux of a target gas, the computer program code effective for being executed by a data processor, the computer program code comprising: computer instructions configured to cause the data processor to receive a plurality of gas density measurement data for the target gas, a plurality of wind speed measurement data, and a plurality of temperature measurement data; computer instructions configured to cause the data processor to determine a raw flux term of the target gas based on the plurality of gas density measurement data for the target gas and the plurality of wind speed measurement data; computer instructions configured to cause the data processor to obtain a sensible heat flux measurement indicative of sensible heat flux during a period of time when the gas density measurement data was obtained; computer instructions configured to cause the data processor to determine a thermal expansion term based on the sensible heat flux measurement and the plurality of temperature measurement data; and computer instructions configured to cause the data processor to determine at least a first multiplication factor based on a response function of the instrument used to obtain the plurality of gas density measurement data, wherein the response function of the instrument relates actual gas density and measured gas density of the target gas as a function of temperature, wherein a gas flux value of the target gas is generated by combining one of the raw flux term or the thermal expansion term with said at least a first multiplication factor.
