corrFluxDensity: corrFluxDensity

In bgctw/RespChamberProc: Processing Data from Respiration Chambers

corrFluxDensity

Description

Calculate total flux inside the chamber from flux per amount of air

Usage

corrFluxDensity(CO2_molarFlux, volume = 1, 
    temp = 20, pressure = 101325)

Arguments

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]

Details

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.

Value

numeric vector (nrow ds): CO2 flux [mumol CO2 /s]

Examples

#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)
