(1) Temperature errors can occur when a sensor is placed too close to a heat source (such as a
building structure, the ground or trees).
To calibrate temperature, we recommend a mercury or red spirit (fluid) thermometer. Bi-metal (dial)
and digital thermometers (from other weather stations) are not a good source and have their own margin
of error. Using a local weather station in your area is also a poor source due to changes in location, timing
(airport weather stations are only updated once per hour) and possible calibration errors (many official
weather stations are not properly installed and calibrated).
