A method of monitoring an unsaturated zone gas and a near-surface atmosphere at a land under which CO2 is stored, the method comprising:

(a) measuring concentration of CO2 at an unsaturated zone in a land to be used to store CO2 under a ground according to time slots in a CO2 concentration detector, transmitting the concentration of CO2 to a monitoring server through a communication device, analyzing information of the concentration of CO2 at the unsaturated zone in the monitoring server, and storing a maximum of the concentration of CO2, which is obtained from a nature, as a reference concentration of CO2 at the unsaturated zone, before CO2 is stored under the ground;
(b) analyzing isotopes of gas contained in a near-surface atmosphere in an isotope analyzer of a near-surface atmosphere analyzer, measuring the concentration of CO2 at the unsaturated zone in the CO2 concentration detector, and transmitting the concentration of CO2 to the monitoring server through the communication device, after the storage of the CO2 under the ground is started;
and
(c) comparing the measured concentration of the CO2 with the reference concentration of CO2 in the monitoring server and outputting a normal signal or an abnormal signal.
