Dear Sir,
I have another question.
I only have the parameter: air temperature, relative humidity, wind speed, and global radiation. And I don`t have the obstacles and svf.
Can I use this parameters to caculate PET?
And I have read the old post, in one post you side it`s ok. In this way, the SVF is 1.
But I still wonder that the result will be different with different SVF. So I draw it in the input>sky view factor. Then I clikc ?new?. The result is different.
So only having climatic parameters without fish eye photos is not enough to caculate PET?

Hope to get your reply.
Best wishes.
