In SPATIAL-Lab/NEONiso: Tools to Calibrate and Work with NEON Atmospheric Isotope Data

Calculate 12C-CO2 Mole Fractions

Description

This function calculates mole fractions of 12CO2 based on the total CO2 mole fraction, the delta13C value of the mixture, and the assumed fraction of CO2 that does not correspond to 12CO2 or 13CO2 (assumed fixed at 0.00474, e.g., Griffis et al. 2004 Agricultural and Forest Meteorology)

Usage

calculate_12CO2(total_co2, delta13c, f = 0.00474)

Arguments

total_co2	Vector of CO2 mole fractions.
delta13c	Vector of d13C values.
f	Fraction of CO2 that is not 12CO2 or 13CO2. Assumed fixed at 0.00474

Value

Vector of 12CO2 mole fractions.
