type="cite">sure, if you have the global radiation in a horizontal
surface (I guess that's the one you have)...you can say<br>
Ig=Id+Ib<br>
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)<br>
you can say that<br>
Id=Ig-DNI*sin(elev)<br>
<br>
you can use a calculator to do so<br>
<br>
regards<br>

<br>
is there any way to obtain diffuse radioation from global radiaton data
to be use to simulation studio?<br>
<br>
thanks in advance<br>
