thanks in advence

En/na Jaime Gonzalez Rodriguez ha escrit:
sure, if you have the global radiation in a horizontal surface (I guess that's the one you have)...you can say
Ig=Id+Ib
where Id and Ib are diffuse and beam irradiances on a horizontal surface, since you have the DNI and the elevation solar angle, and you know that Ib = DNI*sin(elev)
you can say that
Id=Ig-DNI*sin(elev)
you can use a calculator to do so

Hi Trnsys users,
is there any way to obtain diffuse radioation from global radiaton data to be use to simulation studio?
thanks in advance
