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?
yes, of course you can calculate thermal indices based on air temperature, relative humidity (or vapour pressure), wind speed and global radiation. In this case you are assuming, the global radiation is valid for the very location you are calculating for. SVF needs to stay 1.0 in this setting as the global radiation must not be further reduced (otherwise you end up with a double-consideration of the environment).
