Hi.

I think the Thornthwaite model is good for humid regions. However, by calibration the other ET0 models it is possible to reach your aims.

I think, for Iran contrary, Hargreaves method is better, but if you have inputs of FAO Penman-Monteith equation, I recommend it

Soror Esmaeili

Hello

I suggest comparing models such as Hargreaves method--Blaney-Criddle-Linacre and various temperature-based methods with the FAO Penman-Monteith method, and finally selecting the best model and using this method for future research. For my study area, the Blaney-Criddle method was very accurate.

Pritha Datta

Dear Aryan,

I recommend you to use the Hargreaves–Samani (H-S) equation for estimating the PET. You can follow these studies for reference:
