Two temperature formulas are used in the calculation of the PET value:
- The atmospheric temperature Ta
- The wet-bulb temperatur Tw
Atmospheric Temperature formula
Ta,t = Tstation,t + UHImax,t * fsun,t
where,
- Ta,t is the calculated atmospheric temperature at time t;
- Tstation,t is the temperature measured at a weather station at time t;
- UHImax,t is the calculated Urban Heat Island effect at time t;
- fsun,t is the sun daily motion factor at time t;
