Abstract

Aspects of the present disclosure relate to measuring an external temperature using a computing device. In one case, a model for measuring the external temperature may be derived. A solution of the model may be compared with at least one data quantity of a plurality of data quantities to determine a difference between the solution of the model and the at least one of the plurality of data quantities. One or more parameters of the model may be fit such that the difference between the solution of the model and the at least one of the plurality of data quantities is minimized. The external temperature may be measured using the solution of the model.
