Effective prediction of leaf temperatures for orchards
On calm, clear nights leaf temperatures can drop well below air temperature.
A radiation frost occurs when frost forms on the surface before
the air temperature reaches freezing.
The Apogee radiation frost dectector contains a high accuracy thermistor mounted
in a rugged housing.
The thermistor mimics a leaf, which provides estimates of leaf
temperatures when monitoring radiation frost events.
