Baselines: Investigators use a baseline measurement of environmental conditions to determine environmental anomalies during the investigation. Measurements of temperature, radiation, electromagnetic fields, air density and pressure, and others are systematically recorded to determine what’s "normal" about the site; departures from those baselines, therefore, potentially suggest what could be abnormal or paranormal. Many groups use weather, solar and geological data as well, in order to create a baseline for the region of the investigation.
