Calculator for Modeling Apple Fruit Skin Temperature

Please note, this model is for illustration purposes only to show the relative effects of different factors on the fruit skin temperature of apples. It should not be used to make actual orchard management decisions.

It is based upon the energy balance model developed by WSU researchers.

The program code assumes a time of 2 PM.
