Radiation Frost Events 

Know when a radiation frost events occurs – get and alert on potential frost damages to your crops.

At night time if the sky is colder than the ground, there is a continuous flux of radiation to the cold night sky. Surface can get very cold. It is underappreciated how cold surfaces can actually get at night when the sky is clear and there is no wind. Under these conditions, plant leaves and buds surface temperature drops. Radiation frost occurs when leaf and buds surface freezes although air temperature never got below zero °C.

Monitoring leaf and bud surface temperature is a critical factor that every farmer should consider in order to take appropriate action (turn on fans) to protect cropped fields, orchards, vineyards and flowers.
