Information processing device, information processing method, and non-transitory storage medium

An information processing method executed by a computer, comprising:

• acquiring first information about exhaust gas in a predetermined area at a predetermined timing observed by an artificial satellite;
• acquiring second information about exhaust gas of a vehicle that is newly generated in the predetermined area at or after the predetermined timing;
• acquiring third information about weather in the predetermined area at or after the predetermined timing;
• and
• predicting a concentration of the exhaust gas in the predetermined area at or after the predetermined timing based on the first information, the second information, and the third information.

A non-transitory storage medium storing instructions executable by one or more processors and causing the one or more processors to perform functions, wherein the functions includes:

• acquiring first information about exhaust gas in a predetermined area at a predetermined timing observed by an artificial satellite;
• acquiring second information about exhaust gas of a vehicle that is newly generated in the predetermined area at or after the predetermined timing;
• acquiring third information about weather in the predetermined area at or after the predetermined timing;
• and
• predicting a concentration of the exhaust gas in the predetermined area at or after the predetermined timing based on the first information, the second information, and the third information.
