Classification: CPC G  A  Y | IPC G

Claim 5:
6. A carbon dioxide absorption amount estimation method, comprising:
measuring, by a sensor terminal, a plurality of types of mutually-differing environmental information related to a field provided with a sensor terminal, wherein the environmental information includes ground surface temperature, solar radiation amount, air temperature, and relative humidity;
receiving, by a server, the plurality of types of environmental information from the sensor terminal;
referring, by the server, to a corresponding relationship between each of the plurality of types of environmental information and carbon dioxide (CO2) absorption amounts stored in advance in a storage device, for each of the received environmental information to acquire a plurality of CO2 absorption amounts;
comparing, by the server, the plurality of acquired CO2 absorption amounts with each other and selects a minimum value as an estimated value;
transmitting, by the server, information regarding the estimated value to an output device;
displaying, by the output device, the information regarding the estimated value;
storing, by the server, a corresponding relationship defined for each type of plant for a ground surface temperature-CO2 absorption amount corresponding relationship between the ground surface temperature and the CO2 absorption amount and a solar radiation amount-CO2 absorption amount corresponding relationship between the solar radiation amount and the CO2 absorption amount; and
referring, by the server, the corresponding relationships in accordance with the plant cultivated in the field where the sensor is installed.
