Temperature: the weak point of forensic entomology.

Measuring temperature is a key factor in forensic entomology. While noting factors to consider for a posteriori temperature estimation, many studies lack detailed methods or general rules allowing their integration into insect development-time calculations. This article proposes tools for determining the adequacy of weather station temperature datasets versus the local temperature experienced by carrion breeders. The idea is to start from a local scale (i.e., the cadaver) and gradually move to larger scales: at each step, the temperature can be increased, decreased or smoothed by environmental or biological factors. While a one-size-fits-all solution is not feasible for a complex and sensitive issue such as forensic meteorology, this checklist increases the reliability of minimum post-mortem interval (PMImin) estimation and the traceability of the proposed assumption.
