Monthly Weather file format

Hi there,

How can I create a simple weather file which includes only monthly insolation data excluding any hourly or sub-hourly records?

I have data in the format:

Source Location ID City State Country Latitude Longitude Time Zone Elevation
x x x x x x x x x x
Year Month GHI DNI DHI Tdry Twet RH Pres Wspd Wdir Albedo
2011 1 x x x x x x x x x x
2011 2 x x x x x x x x x x
2011 3 x x x x x x x x x x
2011 4 x x x x x x x x x x
2011 5 x x x x x x x x x x
2011 6 x x x x x x x x x x
2011 7 x x x x x x x x x x
2011 8 x x x x x x x x x x
2011 9 x x x x x x x x x x
2011 10 x x x x x x x x x x
2011 11 x x x x x x x x x x
2011 12 x x x x x x x x x x

Thanks!

Dear Paul,

Thanks for the prompt reply!

I am working on a research project which aims to find the optimum sampling rate of insolation data to be used when designing future solar farms. I aim to find a relationship between the quality of insolation data input and the PV array output.

So far I have successfully simulated results for minutely, half-hourly and hourly data, and now want to do the same for monthly data.

I would appreciate it if you could give me any suggestions on how this could be done using SAM?

Thanks alot!

regards,

Eranda.
