Calculate total flux inside the chamber from flux per amount of air
corrFluxDensity(CO2_molarFlux, volume = 1,
temp = 20, pressure = 101325)
CO2_molarFlux |
numeric vector of rate of changes in CO2 dry molar fraction [ppm/s] |
volume |
numeric scalar: volume of the chamber in [m3] |
temp |
numeric vector: temperature inside chamber [degC] |
pressure |
numeric vector: pressure inside chamber [Pa] |
The amount of air or CO2 is determined by the volume, pressure and temperature (universal gas law). Converts concentrations to amount of substance in mol.
numeric vector (nrow ds): CO2 flux [mumol CO2 /s]

#data(chamberLoggerEx1s)
ds <- chamberLoggerEx1s
# here, just to have a column, take concentrations
# aside fromt teh example, the flux should be calculated properly before
CO2_molarFlux <- ds$CO2_Avg
ds$CO2_flux <- corrFluxDensity(CO2_molarFlux, pressure=101*1000) #kPa converted to Pa
plot(ds$CO2_flux)
