1. An aerosol generating device comprising:
a storage configured to store an aerosol source or an aerosol base material for holding the aerosol source;
a load configured to atomize the aerosol source by heat generated by receiving supply of electric power from an electric power source;
a sensor configured to output a value relating to temperature of the load; and
circuitry configured to
perform, in response to a request for generation of aerosol, electric power supplying cycles by supplying electric power from the electric power source to the load; and
determine, based on an index that is a standard deviation or variance of output values of the sensor obtained at different times in a single one of the electric power supplying cycles, occurrence of depletion or shortage of the aerosol source in the storage or the aerosol base material.
