Day/Hour Angle Calculation? was created by JQ_PVS
Hi there! I am using the DISC excel file from rredc.nrel.gov/solar/models/DISC/ to estimate my DNI using GHI. I am trying to understand the model and is unsure of how the day angle and hour angle are being derived. Can someone enlighten me on this?

Thanks!
