Weather Data

What is a good source for US weather data for incorporation into gensky?
(This would be for calibrating the -b & -r parameters).

Thanks!

Hi Mark,

I think (hope) you should get some interesting responses to this question. One source that we have used is TMY2 data. See:

http://rredc.nrel.gov/solar/old_data/nsrdb/tmy2/State.html

for the state by state data files and:

http://rredc.nrel.gov/solar/old_data/nsrdb/tmy2/

for some explanation.

I will warn you that this is raw data and you will need some type of parser to read the files in a sensible way.

Regards,

Hi!

I've used the EPW data files, they're csv tables,
so it is very easy to write a script that automatically
converts the illuminance data to values for gensky:

You also need to check how the data has been formatted:

Hope this helps!
