Dear SAM team,
I have encountered some errors relating to invalid irradiance data recently. The specific message I got are of this type:
out of range global irradiance 1513 W/m2 at time [y:2010 m:5 d:26 h:13], set to zero
Due to cloud enhancement, it is actually possible that the available irradiance can exceed the extraterrestrial irradiance for minutes at a time in extreme cases, see related reads below for readers of this thread. In my case I was simulating the system with minute data, containing such extreme values.
I agree that this message should be thrown to point people to possibly invalid data. However, I think it would make sense to not set the irradiance to zero in that case, but to run the simulation with the actual data, maybe limited to cases where the time-resolution is sub-hourly.
What do you think?
Best regards,
Timo
