Co2 is very crucial for carbon footprint therefor, I try to figure out how we can convert into flux.
Flux is generally expressed as the amount of CO2 emitted per unit mass (or area) of source per time.
Please take a look at Article Measurement of Greenhouse Gas Flux from Agricultural Soils U...
Therein are graphs of concentration of gases versus time during the measurement, and you can convert your readings in ppm to flux using conversion of ppm to mg/m3 https://teesing.com/en/library/tools/ppm-mg3-converter.
to convert CO2 into a flux, you need to measure the rate of CO2 exchange between the atmosphere and the surface or ecosystem of interest. This can be done using techniques such as eddy covariance or chamber measurements.
Eddy covariance is a technique that measures the vertical flux of CO2 (and other gases) between the atmosphere and the surface using fast-response instruments that measure the wind velocity and the concentrations of CO2. This technique provides continuous, high-frequency measurements of CO2 fluxes over large areas.
Chamber measurements, on the other hand, involve placing a chamber over a small area of the surface of interest and measuring the changes in CO2 concentration inside the chamber over time. By calculating the difference in CO2 concentration between the inside and outside of the chamber, and knowing the area of the chamber, the flux of CO2 can be calculated.
Once you have measured the CO2 flux, you can use it to calculate the carbon footprint of a particular activity or system by multiplying the flux by the appropriate conversion factor. For example, the carbon footprint of electricity generation can be calculated by multiplying the CO2 flux from the power plant by the emissions factor for the fuel used.
