1. A glucose sensor system, comprising:
a glucose sensor configured to be at least partially inserted into a host;
a temperature sensor; and
sensor electronics programmed to perform operations comprising:
accessing a glucose signal generated by the glucose sensor, the glucose signal being indicative of a glucose concentration level of the host;
accessing a temperature signal generated by the temperature sensor, the temperature signal being indicative of a temperature of the host;
accessing pattern data, the pattern data describing a relationship between the temperature of the host, a second parameter, and the glucose concentration level of the host; and
determining a temperature-compensated glucose concentration level based at least in part on the glucose signal and the pattern data.
