Claim 1:
2. The carbon dioxide absorption estimation system according to claim 1, wherein at least one of the sensor terminal and the server has a vapor pressure deficit calculation unit for calculating a vapor pressure deficit based on the air temperature and the relative humidity,
wherein the storage unit stores the ground surface temperature-CO2 absorption amount corresponding relationship between the ground surface temperature and the CO2 absorption amount, a the solar radiation amount-CO2 absorption amount corresponding relationship between the solar radiation amount and the CO2 absorption amount, and a vapor pressure deficit-CO2 absorption amount corresponding relationship between the vapor pressure deficit and the CO2 absorption amount as the corresponding relationships,
wherein the CO2 absorption amount acquisition unit acquires a temperature-based estimated value based on the measured ground surface temperature and the ground surface temperature-CO2absorption amount corresponding relationship, a solar radiation amount-based estimated value based on the measured solar radiation amount and the solar radiation amount-CO2 absorption amount corresponding relationship, and a vapor pressure deficit-based estimated value based on the vapor pressure deficit and the vapor pressure deficit-CO2 absorption amount corresponding relationship as the plurality of CO2 absorption amounts, and
wherein the minimum value selection unit selects whichever is least among the temperature-based estimated value, the solar radiation amount-based estimated value, and the vapor pressure deficit-based estimated value as the estimated value.
