Fig. 2. Diagram of the terms used in the scaled method (Eq. [4]). Time t might be any daylight time at which a canopy temperature (Trmt,t) was measured at a remote location in the field. A contemporaneous temperature (Tref,t) from the reference temperature data is then used in Eq. [4] along with the common predawn minimum temperature (Te) and each value in the reference temperature data (Tref) to predict corresponding temperatures at the remote location throughout the daylight hours (Trmt).
