Following publication of the original article (Lee, 2018), it was reported that a mismatch occurred between the online HTML article and the PDF version. In the PDF version of the article, text was missing on page 3 between “Rs was calculated from the rate of increase in CO2 concentration measured per unit of time (Eq. (1)):” and the equation “Rs (mg CO2 m-2 h-1) = a · ρ · V · S-1” (2)

The text from the beginning of page 3 should read as follows:

… AOCC system. Also, AOCC can minimize the artificial disturbance caused by the measurement because there is little access of the measurer around the measuring point. A detailed description of this type of system can be found in Suh et al. (2006) and Eom et al. (2018). Rs was calculated from the rate of increase in CO2 concentration measured per unit of time (Eq. (1)):
$$ \mathrm{Rs}\ \left(\mathrm{mg}\ {\mathrm{CO}}_2\ {\mathrm{m}}^{-2}\ {\mathrm{h}}^{-1}\right)=a\cdotp \rho \cdotp L\cdotp {A}^{-1} $$
(1)

where a is the increasing rate of the CO2 (ppm min− 1) in the closed chamber system, ρ is the density of CO2, L is the total volume of the closed chamber system (m3) included in chamber, tube, IRGA, pump etc., and A is the surface area in the chamber.

In the MCM, the CO2 concentration was measured using a closed chamber cap of approximately 15 cm high that was installed with a CO2 sensor (GMP343, Vaisala, Finland) at the top inner section. When the chamber cap was installed on the collar top, the CO2 concentration in the closed space between the ground and the chamber cap increased with time (Lee, 2018). In the MCM, the Rs was calculated using the following Eq. (2):
$$ \mathrm{Rs}\ \left(\mathrm{mg}\ {\mathrm{CO}}_2\ {\mathrm{m}}^{-2}\ {\mathrm{h}}^{-1}\right)=a\cdotp \rho \cdotp V\cdotp {S}^{-1} $$
(2)

The original article (Lee, 2018) has been updated.
